Léa starts a basketball practice session. The probability that she makes a successful shot is \(0.2\), and we assume all shots are independent. Let \(X\) be the random variable representing the rank of her first successful shot.
State the distribution followed by \(X\).
Represent the situation with a tree diagram for the first three trials and use it to find \(P(X=2)\).
Calculate \(P(X=5)\) and interpret the result.
Calculate \(P(X \leq 3)\) and interpret the result.
Calculate \(E(X)\) and interpret the result.
