Question

Use the probability distribution table to answer the question. What is P(2≤X≤5)? Enter your answer, as a decimal, in the box.

X P
0 0.45
1 0.21
2 0.15
3 0.09
4 0.07
5 0.02
6 0.01

Answer 1

$\mathbb P(2\le X\le5)=\mathbb P(X=2)+\mathbb P(X=3)+\mathbb P(X=4)+\mathbb P(X=5)$

According to the table, we have

$\mathbb P(2\le X\le5)=0.15+0.09+0.07+0.02=0.35$
