What to find?

P(X < 2)

Given:

[tex]P(X<2)=P(X=-2)+P(X=-1)+P(X=0)+P(X=1)[/tex]

From the given table;

P(X=-2) = 0.1

P(X=-1)=0.1

P(X=0)=0.2

P(X=1)=0.2

Substitute the values into the formula above and simplify.

[tex]P(X<2)=0.1+0.1+0.2+0.2[/tex][tex]=0.6[/tex]

Hence, P(X < 2)=0.6

ANSWER

0.6
