The distribution of the binomial random variable (X) has the following parameters p = 0.3 and n = 9. Determine E(X).
To determine E(X) for a binomial random variable, we use the formula:
E(X) = np
Given that p = 0.3 and n = 9, we can plug in these values into the formula:
E(X) = 0.3 * 9
E(X) = 2.7
Therefore, the expected value of the binomial random variable X is 2.7.
