Question

The probability distribution for a random variable x is given in the table X: -5,-3,-2,0,2,3 Probability: .17,.13,.33,.16,.11,.10 Find the probability that X <_-3

Answer 1

Answer:0.3

Explanation:

Answer 2

0.3 probability that
`x \leq -3`

Explanation:

The probability distribution is given in the table.

Probability that x <= -3

The values that are -3 or lower are -3 and -5. So

`P(X \leq -3) = P(X = -3) + P(X = -5)`

From the table:

`P(X = -3) = 0.13, P(X = -5) = 0.17`. So

`P(X \leq -3) = P(X = -3) + P(X = -5) = 0.13 + 0.17 = 0.3`

0.3 probability that
`x \leq -3`
