Consider the following discrete probability distribution a C

Consider the following discrete probability distribution. a. Complete the probability distribution. (Round your answer to 2 decimal places.) c. What is the probability that the random variable X is negative? (Round your answer to 2 decimal places.) Probability d. What is the probability that the random variable X is greater than -25? (Round your answer to 2 decimal places.) Probability e. What is the probability that the random variable X is less than 25? (Round your answer to 2 decimal places.) Probability

Solution

(a) P(X=15) =1-0.46-0.1-0.08 =0.36

------------------------------------------------------------------------------------------------------------------------------

(c) P(X<0)= 0.46+0.1=0.56

------------------------------------------------------------------------------------------------------------------------------

(d) P(X>-25) =0.1+0.36+0.08=0.54

------------------------------------------------------------------------------------------------------------------------------

(e)P(X<25) =0.46+0.1+0.36=0.92
