The area is 25
a= 1/2bh
=1/2(10)(5)
=1/2(50)
For example, if x/2=7, x would be equal to 7x2=14, bringing the whole number the variable is divided by to the other side of the equation.

Conditional Probability
We use the conditional probability formula to solve this question. It is
![P(B|A) = \frac{P(A \cap B)}{P(A)}](https://tex.z-dn.net/?f=P%28B%7CA%29%20%3D%20%5Cfrac%7BP%28A%20%5Ccap%20B%29%7D%7BP%28A%29%7D)
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.
Of the friends who like sprinkles, what proportion of this group likes chocolate:
So,
Event A: Likes sprinkles
Event B: Likes chocolate
15% of your friends like sprinkles (S) topping.
This means that ![P(A) = 0.15](https://tex.z-dn.net/?f=P%28A%29%20%3D%200.15)
5% of your friends like Chocolate (C) and also like sprinkles (S).
This means that ![P(A \cap B) = 0.05](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D%200.05)
So
![P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05}{0.15} = 0.3333](https://tex.z-dn.net/?f=P%28B%7CA%29%20%3D%20%5Cfrac%7BP%28A%20%5Ccap%20B%29%7D%7BP%28A%29%7D%20%3D%20%5Cfrac%7B0.05%7D%7B0.15%7D%20%3D%200.3333)
0.3333 = 33.33% of this group likes chocolate
