The probability of a binomial random variable is given by the formula: $$ P(x) = \binom{n}{x} p^x (1-p)^{n-x} $$. For $ n = 4 $, $ x = 2 $, and $ p = 0.2 $, the calculation is: $$ P(2) = \binom{4}{2} (0.2)^2 (0.8)^2 = 6 \times 0.04 \times 0.64 = 0.1536 $$.

If x is a binomial random variable, compute p(x) for n=4,x=2,p=0.2. \text { If } x \text { is a binomial random variable, compute } p ( x ) \text { for } n = 4 , x = 2 , p = 0 \text {.2. } If x is a binomial random variable, compute p(x) for n=4,x=2,p=0.2.
