Answer:
52.5% probability that A occurs given B occurs
Step-by-step explanation:
Suppose we have two events, A and B, the conditional probability formula is:
![P(A|B) = \frac{P(A \cap B)}{P(B)}](https://tex.z-dn.net/?f=P%28A%7CB%29%20%3D%20%5Cfrac%7BP%28A%20%5Ccap%20B%29%7D%7BP%28B%29%7D)
In which
P(A|B) is the probability of A happening given that B happened.
is the probability of both A and B happening.
P(B) is the probability of B happening.
In this problem, we have that:
![P(A \cap B) = \frac{3}{8}, P(B) = \frac{5}{7}](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D%20%5Cfrac%7B3%7D%7B8%7D%2C%20P%28B%29%20%3D%20%5Cfrac%7B5%7D%7B7%7D)
So
![P(A|B) = \frac{P(A \cap B)}{P(B)} = \frac{\frac{3}{8}}{\frac{5}{7}} = 0.525](https://tex.z-dn.net/?f=P%28A%7CB%29%20%3D%20%5Cfrac%7BP%28A%20%5Ccap%20B%29%7D%7BP%28B%29%7D%20%3D%20%5Cfrac%7B%5Cfrac%7B3%7D%7B8%7D%7D%7B%5Cfrac%7B5%7D%7B7%7D%7D%20%3D%200.525)
52.5% probability that A occurs given B occurs
Answer:
y=69420
Step-by-step explanation:
f=42×0=420
b=6+9=69
i=91÷1=911
It would equal 1,000 because you would have to multiply 10 3 times 10 to the 3rd power = 10 x 10 x 10
Answer: No
Step-by-step explanation: The length isn't 90 degree's so it can't be a right triangle
