Answer:
P(A/B) is called the CONDITIONAL PROBABILITY of occurring of event A when event B has already taken place.
![P(A/B) = \frac{P(B/A) . P(A)}{P(B)}](https://tex.z-dn.net/?f=P%28A%2FB%29%20%3D%20%5Cfrac%7BP%28B%2FA%29%20.%20P%28A%29%7D%7BP%28B%29%7D)
Step-by-step explanation:
Let us assume there are two given events A and B.
The probability of A when B has occurred is given as P (A/B).
The probability of B when A has occurred is given as P (B/A)
Also, the probability of occurring A independently = P(A)
The probability of occurring B independently = P(B)
Now, the BAYES THEOREM gives us the exact formula to determine the CONDITIONAL PROBABILITY.
By Bayes Formula:
![P(A/B) = \frac{P(B/A) . P(A)}{P(B)}](https://tex.z-dn.net/?f=P%28A%2FB%29%20%3D%20%5Cfrac%7BP%28B%2FA%29%20.%20P%28A%29%7D%7BP%28B%29%7D)
Here, P(A/B) is called the CONDITIONAL PROBABILITY of occurring of event A when event B has already taken place.
Answer:
1670
Step-by-step explanation:
Mas has 839 balls
37 are taken away
839 -37 = 802
Then he gets 868 balls
802+868 =1670
He now has 1670 balls
J/6 = 9/10 is the proportion that we are trying to solve. Let's use cross products, or multiplying the numerator of one fraction by the denominator of the other fraction, and setting these two numbers equal to one another in an equation.
9 (6) = 10 (j)
When we combine like terms (multiply), we get
54=10j
We need to divide both sides by 10, to get the variable alone.
j = 5.4
Percent is /100
5/20 weigh more than 8 lbs
Times both sides by 5 and get 25/100 so 25%
Answer:
C =31.4 inches
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
C = 2 * 3.14 * 5
C =31.4 inches
