Answer: hope it help u mark as brainalist answer
Explanation: The sample space of the experiment is S = {HH, HT, TH, TT}. Let X is the number of tails and It takes up the values 0, 1 and 2. Now, P(no tail) = p(0) = \frac{1}{4}, P(one tail) = p(1) = \frac{2}{4} and P(two tails) = p(2) = \frac{1}{4}. So, X is the number of tail runs and it takes up the values 0 and 1. P(X = 0) = p(0) = \frac{2}{4} = \frac{1}{4}.
