Answer:
P(A given B) = 3/4
Step-by-step explanation:
As we know that it is conditional probability, where the probability of an event depends on the event that has certain probability of occurrence.
The formula for conditional probability is:
P(A given B) = P(A ∩B) / P(B)
Where a and B are events. The probability of event B is known and we also know probability of A∩B
So, putting the values in the formula:
![P(A\ given\ B) = \frac{P(A and B)}{P(B)}\\= \frac{\frac{3}{10} }{\frac{2}{5} } \\=\frac{3}{10} *\frac{5}{2}\\=\frac{3}{4}](https://tex.z-dn.net/?f=P%28A%5C%20given%5C%20B%29%20%3D%20%5Cfrac%7BP%28A%20and%20B%29%7D%7BP%28B%29%7D%5C%5C%3D%20%5Cfrac%7B%5Cfrac%7B3%7D%7B10%7D%20%7D%7B%5Cfrac%7B2%7D%7B5%7D%20%7D%20%5C%5C%3D%5Cfrac%7B3%7D%7B10%7D%20%2A%5Cfrac%7B5%7D%7B2%7D%5C%5C%3D%5Cfrac%7B3%7D%7B4%7D)
So, the probability of A given B is 3/4 ..
Answer: $29
Step-by-step explanation: this is the easiest way to explain it-
20= 100%
10=50%
5=25%
10 is 50
9 is 45
8 is 40
7 is 35
6 is 30
5 is 25
Answer:
40%
Step-by-step explanation:
(21-15)/15=0.4
0.4×100=40
Answer:
$71.40
Step-by-step explanation:
Turn the percentage 30 to a decimal, which is 0.3 then multiply it by 238 to get 71.4
