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
