According to the general equation for conditional probability, if (image attached)

a. 2/3
b. 1/3
c. 1/6
d/ 5/6

Option B

Step-by-step explanation:

If B 'is the complement of B then

In a probabilistic experiment, when two events A and B are dependent on each other, then the probability of occurrence A since B occurs is:

Then if and

The correct answer option is B. 1/3.

Step-by-step explanation:

We are given that P (A ∩ B') = 2/9 and P (B') = 1/3 and we are to find P (A | B').

We also know that the formula of conditional probability is given by:

P (A | B') = P (A ∩ B') / P (B)

So substituting the given values in the formula above to get the value of P (A | B'):

P (A | B') = = 1/3

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
