A probability that a bulb produced by a factory will fuse after days of use is . What is the probability that out of such bulbs none will fuse after days of use
Explanation for the correct option:
Step 1: Find the probability that the bulb will not fuse:
Subtract the probability of bulb will fuse to unity.
Given: The probability of bulb will fuse
So, the probability that the bulb will not fuse
Step 2: Use binomial distribution to find the required probability:
Find the binomial coefficient for
Hence, option (B) is the correct answer.
