Answer:
B) 3/4
Step-by-step explanation:
The conditional probability of B given A (B|A) is P(A ∩ B) / P(A), when P(A) > 0 (Probability of the intersection of A and B over the Probability of A).
in our case, P(A ∩ B is the amount of people who can snowboard and surf, which according to the picture is 36
P(A) is the amount of people who can snowboard, which from the picture is 48
This means our conditional probability is 36/48, which when simplified is 3/4.
The answer is 90, Because angle D is a 90 degree angle, and 180- 90=90, so the answer is 90.

Explanation
Factor the numerator and denominator and cancel the common factors.
<h2>
1. y-intercept</h2>
The quadratic function 
represents a parabola. In fact, the graph of a quadratic function is a special type of U-shaped curve called a parabola. To find the y intercept, we set 
as follows:
<h2>
2. x-intercepts</h2>
To find the other x-intercept, we must set 
as follows:
Therefore, the other x-intercept is 
. You can see both the y-intercept and the x-intercepts in the figure below.
