The probability that a data communications system will have high selectivity is 0.72, and the probability that it will have high

34kurt

Let us assume that even F represents fidelity and event S represents selectivity.

We have been given the probabilities:

P(S) = 0.72, P(F) = 0.59 and $P(S\cap F)=0.33$

We need to find the conditional probability that a system with high fidelity will also have high selectivity. We know the conditional probability formula:

$P(\frac{S}{F})=\frac{P(S\cup F)}{P(F)}$

Upon substituting the given values, we get:

$P(\frac{S}{F})=\frac{0.33}{0.59}$

$P(\frac{S}{F})=\frac{33}{59}=0.56$
