Suppose that E and F are two events and that P(E)= 0.7 and P(FIE) = 0.3. What is P(E and F)? P(E and F) = (Simplify your answer.)

Answers

Answer 1

The calculated value of P(F|E) is 0.4.

Then the conditional probability that the event  will occur given that  has already occurred is given by the following formula:

P(B|A) = (P(A∩B)) / P(A)

Here the two events given are E and F .

P(E and F) or P(E∪F) = 0.3

and P(E)= 0.7

As per the above formula that we have already discussed, the formula can be written as:

P(F|E) = P(E ∩ F) / P(E)

P(F|E) =0.3/0.7

P(F|E) = 3/7

P(F|E) = 0.4

What in likelihood are E and F?

The capital letters E and F in the discussion that follows stand in for potential experiment results, and P(E) denotes the likelihood that outcome E will be seen. The results of E or F can be listed as the results of E followed by the results of F for events that don't happen simultaneously.

How can you demonstrate the independence of two events?

If knowing whether A happened has no effect on the likelihood that B will also occur, then events A and B are independent. Mathematically, the following statements are equivalent: P(A and B) = P(B A) = P(B) P(B|A) = P(B) (A).
