Question

Find the probability. PLZ HELP

Answer 1

Probability that
`-5 \leq x \leq 5` is 0.3

Explanation:

From the table, we have that the probability is:

`P(-5 \leq x \leq 5) = P(x = -5) + P(x = 0) + P(x = 5)`

With the values given

`P(-5 \leq x \leq 5) = P(x = -5) + P(x = 0) + P(x = 5) = 0.15 + 0.05 + 0.1 = 0.3`

So

Probability that
`-5 \leq x \leq 5` is 0.3
