A dice is thrown times then the probability that an even number will come up exactly times is
An explanation for the correct option:
Step 1: Find the probability of success and failure.
We have been given a dice is thrown times.
We need to find the probability that an even number will come up exactly times.
the probability of getting an even number
the probability of getting an odd number
Step 2: Using the formula of Binomial distribution, find the required probability.
the probability that an even number will come up exactly times is:
here,
Therefore, option (A) is the correct answer.
