A college student is taking two courses. The probability she passes the first course is 0.7. The probability she passes the second course is 0.67. The probability she passes at least one of the courses is 0.79. Give your answer to four decimal places. a. What is the probability she passes both courses

0.58 = 58% probability she passes both courses

Step-by-step explanation:

We have two events, A and B.

In which:

is the probability of at least one of these events happening.

P(A) is the probability of A happening.

P(B) is the probability of B happening.

is the probability of both happening.

In this question:

Event A: Passes the first course.

Event B: Passes the second course.

The probability she passes the first course is 0.7.

This means that

The probability she passes the second course is 0.67.

This means that

The probability she passes at least one of the courses is 0.79.

This means that

What is the probability she passes both courses

0.58 = 58% probability she passes both courses

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
