Help on this I got this wrong
1 answer:
Check the picture below.
recall, AB = AC, and AR is an angle bisector to the vertex A, so A gets split into two equal angles, so those angles are twins.
now, the segment AR is part of triangle ABR and is also part of the triange ACR, however, is being shared by both, and therefore, is the same length on each triangle.
so you have a Side, in green, an Angle, from the twins, and another Side, being shared by both, Side Angle Side, SAS.

Answer:
0.3333 = 33.33% of this group likes chocolate
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.
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
5% of your friends like Chocolate (C) and also like sprinkles (S).
This means that
So
0.3333 = 33.33% of this group likes chocolate
