Question

According to the general equation for conditional probability, if p(a^

Answer 1

This is the concept of probability and statistics;
The question requires us to get the conditional probability is given by:
P(A|B)=(P(A∩B))/P(B)
but;
P(A∩B)=3/10
P(B)=4/5
thus;
P(A|B)=(3/10)/(4/5)=3/8
The answer is 3/8

Answer 2

Answer:

$\frac{3}{8}$

Step-by-step explanation:

Since, the general equation of conditional probability is,

$P(\frac{A}{B})=\frac{P(A\cap B)}{P(B)}$

We have,

$P(A\cap B)=\frac{3}{10}$

$P(B)=\frac{4}{5}$

By substituting the values,

$P(\frac{A}{B})=\frac{\frac{3}{10}}{\frac{4}{5}}$

$=\frac{5\times 3}{10\times 4}$

$=\frac{15}{40}$

$=\frac{3}{8}$

Hence, the value of P(A∩B) is 3/8.
