Events a and b are independent. find the missing probability

p(a)=1/4 p(b)=3/5 p(b/a)=?

Explanation:

P(B/A) is the shorthand way of saying "what is P(B) if we are 100% certain that event A has occured?"

Because events A and B are independent, they do not affect one another. The fact that A happens doesn't change P(B) at all.

Therefore, P(B) = P(B/A) when A & B are independent events.

Similarly, P(A) = P(A/B) when the two events are independent.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
