After manufacture, computer disks are tested for errors. Let X be the number of errors detected on a randomly chosen disk. The following table presents values of the cumulative distribution function F(x) of X.
a. What is the probability that two or fewer errors are detected?
b. What is the probability that more than three errors are detected?
c. What is the probability that exactly one error is detected?
d. What is the probability that no errors are detected?
e. What is the most probable number of errors to be detected?
Step 1 of 3
We have computer disks are tested for errors After manufacture. Let us consider the random variable X it presents the number of errors detected on a randomly chosen disk. We have table that presents values of the cumulative distribution function F(x) of X.

Our goal is:
a).We need to find What is the probability that two or fewer errors are detected?
b).We need to find What is the probability that more than three errors are detected?
c).We need to find What is the probability that exactly one error is detected?
d).We need to find What is the probability that no errors are detected?
e).We need to find What is the most probable number of errors to be detected?
