Answer:

c. step three

Step-by-step explanation:

CORRECT WAY

step one: -7/ -2 / 4/9 (flip 4/9)

step two: -7/-2 * 9/4 (simplify)

step three: = 63/8

Step three is incorrect because it's not - it's positive.

She forgot that a negative divided by a negative is a positive.

So -7/-2 is the same as 7/2

Hope this helps ya!!!

Answer:

P ( snowboard I ski)​ = 0.5714

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Ski

Event B: Snowboard.

28 out of 120 students ski:

This means that P(A) = \frac{28}{120} = 0.2333

16 out of 120 do both:

This means that P(A \cap B) = \frac{16}{120} = 0.1333

P ( snowboard I ski)​

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.1333}{0.2333} = 0.5714

So

P ( snowboard I ski)​ = 0.5714
