a) In a binomial distribution containing of 10 independent trials, probability of 1 and 2 successes are 0.3874205 and 0.937102respectively. Find the parameter p of the distribution. b) Suppose X is a binomial random variable with parameters of n=3 and p. If P(X= 1) = 0.3, P(X= 2) = 0.2 and P(X = 0) = 3P (X= 3). Find E(X).
