### What is the probability that the difference of the two (2) numbers drawn is 10 or less?

After one number, a, is drawn, 49 remain. Let's suppose a=1, then the numbers 2-11 (10 tickets) would satisfy the criterion that b, the second number, satisfies |b-a|≤10. So that's 10/49. If a=2, then if b=1 or 3≤b≤12 |b-a|≤10. That's 11 tickets, 11/49. If a=25, 15≤b≤24 or 26≤b≤35, that's 20 tickets, 20/49. If a=30, then 20≤b≤29 or 31≤b≤40, 20 tickets again, 20/49. The rule is then that for 11≤a≤40 the probability for b is 20/49. The probability of picking a in range for this probability for b is 30/50. The combined probability is 30/50*20/49=12/49.  At the other end of the scale for 50≥a≥41 we have the same probabilities as for 1≤a≤10; when a=50, b can be 40-49 (10 tickets); when a=49, b can be 50 or 39-48 (11 tickets), and so on. We can put together a 50X50 table, but we can also summarise it: ("Y" means "yes, the values of 'a' (row number) and 'b' (column number) represented by this little square satisfy |a-b|≤10".) The small square with the red diagonal represents the whole of the large table on the left, which is only shown up to its 40th row. The red diagonal, containing X's for no-go, or disallowed combinations, excludes a=b. One way of calculating probability is to work out the fraction (number of "successful " events) ÷ (total possible number of events). This is the same as dividing the "area" occupied by Y's in the table by the "area" of the table itself, excluding the red diagonal. This is better represented by the small square with the red diagonal. This approach of using areas is the fastest way to arrive at the probability and it's easy to calculate: Area of table=50^2-50=2450=50*49 (there are 50 red squares in the red diagonal to be removed). Area of a trapezoidal corner piece=19+18+...+10=145. Total area of both trapezoids=290. (The right-angled trapezoids are formed by the Y's in rows a=1 to 10 and b=1 to 20, and a=41 to 50 and b=31 to 50. The trapezoid consists of a 10X10 square=100, less the diagonal of 10, which makes 90; and a right-angled triangle containing 55 Y's. Total 145. Not the usual way of calculating the area of a triangle!) Area of central "parallelogram"=30*20=600. Total area of Y's (central band)=890. So the probability of picking two numbered tickets, the difference of which is 10 or less, is 890/2450=89/245. In case you're not convinced that this simple solution is correct, let's go back to the calculations at the beginning. For any particular value of a there's always a 1/50 probability of picking it, but, depending on the value we have varying probabilities for b. Take a=1: the combined probability of |a-b|≤10 is 1/50*10/49; for a=2 it's 1/50*11/49, giving us the progression: 1/50*10/49+1/50*11/49+1/50*12/49+...+1/50*19/49. This also applies to a=50, a=49, ..., a=41. The total probability for the "ends" is (2/2450)(10+11+12+...+19)=2*145/2450. In the "middle section" we have constant 20/49 for b in the range 11≤a≤40=30/50*20/49=600=600/2450. The total is (290+600)/2450=890/2450=89/245. So the figures match the "areas".

### Kirsty's school locker has a two-digit number on it.

Question: Kirsty's school locker has a two-digit number on it. The sum of the two digits is 10 and their difference is 2.  If the locker number is less than 50, what number is it? Let the two digits be d1 and d2. Then d1 + d2 = 10 d2 - d1 = 2  (one of the digits will be larger than the other, so call that one d2) add together the above two equations. This gives us, 2*d2 = 12   - now divide both sides by 2 d2 = 6, hence d1 = 4 The digits on the locker are 6 and 4. So the locker number itself must be 46 or 64. Since we are told that the locker number is less than 50, then the locker number must : 46

### Which statement is true based on the data above?

Jacqueline practiced drums four times last week for sessions of 40 minutes, 35 minutes, 45 minutes, and 30 minutes. Cassie practiced five times last week for sessions of 15 minutes, 30 minutes, 15 minutes, 15 minutes, and 50 minutes. Which statement is true based on the data above?   1)      The two girls practiced for the same total amount of time last week.    ----- FALSE! Jacqueline practiced for sessions of:  40 + 35 + 45 + 30 = 75 + 75 = 150 minutes. Cassie practiced for sessions of: 15 + 30 + 15 + 15 + 50 = 45 +30 + 50 = 75 + 50 = 125 minutes. The two girls practised for different lengths of time last week.   2)      The average length of time Cassie spent practicing is greater than the average length of time Jacqueline spent practicing.   ---- FALSE Jacqueline practiced for 150 minutes over 4 sessions, gives av. = 37.5 minutes Cassie practiced for 125 minutes over 5 sessions, gives av. = 25 minutes. Cassie spent less time practising than Jacqueline. 3)   The difference in length between Cassie’s longest and shortest practice sessions was greater than the difference in length between Jacqueline’s longest and shortest sessions.    ------ TRUE. Jacqueline’s longest session = 45 mins. Shortest session = 30 mins. Difference = 15 mins. Cassie’s longest session = 50 mins. Shortest session = 15 mins. Difference = 35 mins. Cassie’s diff (35 mins) is greater than Jacquie’s. 4)   The greatest amount of time either girl spent practicing was one of Jacqueline’s practice sessions.    ----- FALSE Jacquie’s greatest time = 45 mins. Greates time spent by Cassie was 50 mins, greater than Jacquie’s max.
