# 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)

**Solution:**

Probability is defined as the number of favorable outcomes by the total number of outcomes

(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 1 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 4 events of getting an ace.

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

(c) Total number of apples = 7

Number of red apples = 4

So, probability of getting red apple = 4/7
