Question

The probability distribution for the random variable X is given below. Find the probability of P(X<1).X-valueP(X)10.320.230.140.1550.25Write your answer as a decimal.

Answer 1

Given the table, we are asked to the probability of P(X < 1)

Table:

X-value 1 2 3 4 5

P(X) 0.3 0.2 0.1 0.15 0.25

Since:

P(X<1) means all values that are less than 1.

So,

P(X<1) = 0

Therefore, the probability of P(X<1) = 0
