Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The first step you need to do is plug in the numbers...

4(5)+(-4)

Then you will distribute the positive 1 but that won't change much...

4(5)-4

Then you'll have to multiply the 4 and 5 to get....

20 -4

Now from here should be a piece cake, so the answer is...

<h3>Answer: Choice C</h3>

P = 11/40 + 1/4 - 1/20

=========================================================

Explanation:

The formula we use is

P(A or B) = P(A) + P(B) - P(A and B)

In this case,

  • P(A) = 22/80 = 11/40 = probability of picking someone from consumer education
  • P(B) = 20/80 = 1/4 = probability of picking someone taking French
  • P(A and B) = 4/80 = 1/20 = probability of picking someone taking both classes

So,

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 11/40 + 1/4 - 1/20

which is why choice C is the answer

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

Note: P(A and B) = 1/20 which is nonzero, so events A and B are not mutually exclusive.
