Answer: the probability that x is smaller or equal to 0 is 0.79

Step-by-step explanation:

Find the probability that x is smaller or equal to 0

In the table the number that are smaller or equal to 0 are -5,-3,-2,0

And we are given the probability of each number

So all you have to do is add all the probability of the number that are smaller or equal to 0:

0.17 + 0.13 + 0.33 + 0.16 = P
0.79 = P

Answer:

0.79

Step-by-step explanation:


p(x \leqslant 0) = p( - 5) + p( - 3) + p( - 2) + p(0)


= 0.17 + 0.13 + 0.33 + 0.16


= 0.79

Hope this helps...

Best regards!!
