- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Given, In a random experiment of throwing 5 coins, the number of heads is defined as a random variable, so making the table of probability function we get, XPX01234512552510251025525125 Now we know that the mean of the random variable is ∑n=15XnPXn So,…
