Let *P*(*E*) = 0.45, *P*(*F*) = 0.4, and *P*(*F* ∩ *E*) = 0.25. Draw a Venn diagram and find the conditional probabilities.

(a) *P*(*E* | *F*^{C} )

(b)*P*(*F* | *E*^{C} )

(b)

Enter the exact rational fraction, or decimal equivalent rounded to 6 decimal places

Step 1

Here, P(E)=0.45, P(F)=0.4, P(F∩E)=0.25.

Step 2

**Venn diagram:**

P(E) = 0.2 (=0.45-0.25), P(F) = 0.15 (=0.4-0.25), P(F∩E) = 0.25 and U= 0.4 (1- P(E)- P(F)- P(F∩E)).

Step 3

**Conditional probability of two events:**

The conditional probability is the probability of one event given that the other event has already occurred.

Consider two events...
