Enter your answer in the box.

ANSWER: 0.2

Answer 1

ANSWER

P(X=4 or X=1)=0.2

EXPLANATION

From the table, the probability that X=4 is P(X=4)=0.15

and the table, the probability that X=1 is P(X=1)=0.05

We want to find P(X=4 or X=1)

Recall that

P(X=4 or X=1)=P(X=4)+P(X=1)

We substitute the given probability values to obtain:

P(X=4 or X=1)=0.15+0.05

P(X=4 or X=1)=0.2
