Step-by-step explanation:
yes yours answer is correct .
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

In which
P(B|A) is the probability of event B happening, given that A happened.
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 
16 out of 120 do both:
This means that 
P ( snowboard I ski)

So
P ( snowboard I ski) = 0.5714
Use the formula, l•w (length times width)
The length is 97 and the width is 14
97•14=1358
In order to get the constant of variation, you can either
make a linear equation that relates x and y in which the slope is the constant
of variation
LINEARIZING
x = 3y
the slope of the equation is 3 and therefore the constant of
variation is 3
