Question

(a) One ball is selected at random from the bag.

Write down the probability that it is numbered 8

(b) On another occasion, two balls are selected at random from the bag.

Find the probability that:
(i) the number on each ball is even,
(ii) the sum of the numbers on the balls is not more than 10.

​

Answer 1

a) The probability is 1/5

bi) The probability each ball is even will be 2/5

bii) The probability the sum of the numbers on the ball is not more than 10 is 16/25

(that's what I think it is)
