Consider the following data: x −4 −3 −2 −1 0 P(X=x) 0.3 0.1 0.2 0.2 0.2 Step 4 of 5 : Find the value of P(X>−3). Round your answer to one decimal place.

Respuesta :

Answer:

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.
