Binomial Distribution

Let the probability of tail = and the probability of head = . Since the total probability must be 1: Thus, Let be the number of tails in 3 tosses. Then follows a Binomial distribution: The probability distribution of is given by: Now compute each: - - - - Probability distribution table: Mean of the distribution: % Final Answer Final Answer: The probability distribution is as shown above, and the mean of the distribution is .
