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)}](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.
In this question:
Event A: Likes sprinkles
Event B: Likes chocolate
25% of your friends who like Chocolate (C) also like sprinkles (S).
This means that ![P(A \cap B) = 0.25](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D%200.25)
40% of your friends like sprinkles (S) topping.
This means that ![P(A) = 0.4](https://tex.z-dn.net/?f=P%28A%29%20%3D%200.4)
Of the friends who like sprinkles, what proportion of this group likes chocolate
![P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.25}{0.4} = 0.625](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%7B0.25%7D%7B0.4%7D%20%3D%200.625)
The proportion of this group that likes chocolate is 0.625.
