Question

You are given the following probability distribution for the random variable X. Find P(X≤5)? Write your answer as a decimal.X-valueP(X)- 1 is 0.22 is 0.23 is 0.34 is 0.25 is 0.1sorry dont have pic of this problem, hope you can help me figure it out. thank you

Answer 1

The probability of X<=5 is the addition of the probabilities of getting 1, 2, 3, 4, 5.

Then,

`P(X\le5)=P(1)+P(2)+P(3)+P(4)+P(5)=1`

Therefore, the answer is P(X<=5)=1
