Solved Example on Success

Ques: A coin is tossed 5 times. If 'getting a head' is considered as a success, find the probability of at least 3 successes.

Choices:

A.1/6 
B. 1/4
C.1/8 
D. 1/2 
Correct Answer: D

Solution:

Step 1: In a single trial, probability p of success is given by p = P (getting a head) =1/2 .
Step 2: Probability of failure, q = 1 - p = 1 -1/2 = 1/2.
Step 3:[Binomial distribution.] 
Step 4: P(r) = p(3) + p(4) + p(5) 
Step 5:
