Answer:
P(B|A)=y
Step-by-step explanation:
The complete question is shown in the attachment.
If the events, A and B are independent, then
P(A and B) = P(A)×P(B)
But from the question:
P(A)=x and P(B)=y
This implies that:
P(A and B) = xy
Also, the conditional probabilities are:
P(A\B)=P(A)=x
P(B\A)=P(B)=y
Therefore the correct answer is A

Answer:
x=12, y=30
Step-by-step explanation:
to find x:
in a equilateral triangle, all three sides are congruent, so:
4x-4=3x+8
x-4=8
x=12
to find y:
in an equilateral triangle, all the angles are 60°, so:
2y=60
y=30°
