Question

Algebra 2 question: What is the value of P(X=4 or X=1)?

Answer 1

ANSWER

P(X=4 or X=1)=0.20

EXPLANATION

From the probability distribution table,

p(X=4)=0.15

p(X=1)=0.05

We want to find the value of

P(X=4 or X=1).

Recall that:

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

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

We substitute the probability values;

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

P(X=4 or X=1)=0.20
