Question

1. The random variable X has the probability distribution given in the table. \begin{tabular}{|c|c|c|c|c|c|} \hline x & 0 & 5 & 10 & 15 & 20 \\ \hline P(X = x) & & 0.1 & & 0.2 & 0.1 \\ \hline \end{tabular} (a) Assuming $P(X = 10)$ is twice the $P(X = 0)$, find each of the missing values. (b) Calculate $P(X < 15)$.

          1. The random variable X has the probability distribution given in the table.
\begin{tabular}{|c|c|c|c|c|c|}
\hline
x & 0 & 5 & 10 & 15 & 20 \\
\hline
P(X = x) &  & 0.1 &  & 0.2 & 0.1 \\
\hline
\end{tabular}
(a) Assuming $P(X = 10)$ is twice the $P(X = 0)$, find each of the missing values.
(b) Calculate $P(X < 15)$.

1. The random variable X has the probability distribution given in the table.

x 0 5 10 15 20

P(X = x) 0.1 0.2 0.1

(a) Assuming P(X = 10) is twice the P(X = 0), find each of the missing values.
(b) Calculate P(X < 15).
