P (X>-3) = 0.6

Step-by-step explanation:

x p (x)

-4 0.3

-3 0.1

-2 0.2

-1 0.2

0 0.2

We have to find P (X>-3). The value greater than - 3 are - 2,-1 and 0. So, we the P (X>-3) can be computed as

P (X>-3) = P (X=-2) + P (X=-1) + P (X=0)

We are given that

P (X=-2) = 0.2,

P (X=-1) = 0.2

and

P (X=0) = 0.2

So,

P (X>-3) = 0.2+0.2+0.2

P (X>-3) = 0.6

Thus, the required value of P (X>-3) is 0.6.
