Question

The graph show the probability distribution of a random variable.

What is the value of P(0 ≤X ≤4)?
0.40
O 0.45
O 0.50
O 0.55

Answer 1

O 0.50

Explanation:

when x = 0, the probability is 0

when x = 1, the probability is 0.1

when x = 2, the probability is 0.2

when x = 3, the probability is 0.125

when x = 4, the probability is 0.05
