Suppose that 10% of all students at Cooley High play a winter sport, that 20% play a spring sport, and that 5% play both a winter and a spring sport. What is the probability that a randomly chosen student plays a winter or a spring sport?
a. 30%
b. 25%
c. 35%
d. 20%
e. None of the above

b. 25%

Step-by-step explanation:

I am going to say that:

A is the probability that a student plays a winter sport.

B is the probability that a student plays a spring sport.

We have that:

In which a is the probability that a student plays a winter sport both not a spring sport and is the probability that a student plays both a winter and a spring sport.

By the same logic, we have that:

5% play both a winter and a spring sport.

This means that

20% play a spring sport

This means that

10% of all students at Cooley High play a winter sport

This means that

What is the probability that a randomly chosen student plays a winter or a spring sport?

So the correct answer is:

b. 25%

think about the doctor who treated the major and the speaker in the short story "in another country." put yourself in the shoes of the doctor, and based on what you read in the story, write what you think his thoughts about the major and the speaker would be. use the following vocabulary in your response and change the form of these words as needed: detached resign withered
