The probability distribution for a
Tpy6a [65]

Answer:

P(x \le -3) =0.30

Step-by-step explanation:

Given

The attached probability distribution of x

Required

Find P(x \le -3)

To do this, we consider all values of x less than or equal to-3.

So, we have:

P(x \le -3) =P(x=-5) + P(x = -3)

From the table:

P(x=-5) = 0.17

P(x = -3) = 0.13

So, the equation becomes

P(x \le -3) =P(x=-5) + P(x = -3)

P(x \le -3) =0.17 + 0.13

P(x \le -3) =0.30
