Explanation / Answer

a) Probability of sum less than 4 or greater than 8

= P(Sum = 2) + P(Sum = 3) + P(Sum = 9) + P(Sum = 10) + P(Sum = 11) + P(Sum = 12)

= 10/1000 + 30/1000 + 140/1000 + 120/1000 + 80/1000 + 70/1000

= 450/1000 = 0.45

b) Probability that the sum is even or exactly divisible by 3 =

P(Sum = 2,3,4,6,8,9,10,12) = (10 + 30 + 50 + 110 + 170 + 140 + 120 + 70)/ 1000 = 700/1000 = 0.7

Hence the answers are

a) 0.45

b) 0.70
