(8r+3s)(8r-3s) dont have working but noticed that it is the difference of two squares
Sum of infinite series of a GS is a1 / (1-r)
so here it is 65 / (1 - 1/6) = 65 / 5/6 = 65*6 / 5 = 78 answer
Answer:
first one is 8 second one is 7
Step-by-step explanation:
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 
We need to find the conditional probability that a system with high fidelity will also have high selectivity. We know the conditional probability formula:

Upon substituting the given values, we get:
