(b) Outcomes of event of not getting a prime number are 1, 4 and 6.

(ii) (a) Outcomes of event of getting a number greater than 5 is 6.

(b) Outcomes of event of not getting a number greater than 5 are 1, 2, 3, 4
and 5.

3. Find the:

(a) Probability of the pointer stopping on D in (Question 1 (a)).

(b) Probability of getting an ace from a well shuffled deck of 52
playing cards.

(c) Probability of getting a red apple. (See figure below)

Ans. (a) In a spinning wheel, there are five pointers A, A, B, C, D. So there

are five outcomes. Pointer stops at D which is one outcome.

So the probability of the pointer stopping on D =1/5

(b) There are 4 aces in a deck of 52 playing cards. So, there are four
events of getting an ace.

So, probability of getting an ace =4/52 = 1/13

(c) Total number of apples = 7
