If \(x\) is a binomial random variable, compute \(P(x)\) for each of the following cases:
(a) \(P(x \le 1)\), \(n = 4\), \(p = 0.8\)
\(P(x) =\)
(b) \(P(x > 2)\), \(n = 3\), \(p = 0.7\)
\(P(x) =\)
(c) \(P(x < 2)\), \(n = 7\), \(p = 0.7\)
\(P(x) =\)
(d) \(P(x \ge 2)\), \(n = 3\), \(p = 0.1\)
\(P(x) =\)
