probability distribution

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 -2≤x≤2

Answer 1

For the table:

the probability between (and including) -2 and 2 is 0.33 + 0.16 + 0.11 which equals 0.60 or 60%
