Suppose that E and F are two events and that P(E)=0.2 and P(F|E)=0.5 What is P(E and F)?

By definition of conditional probability,

P(F | E ) = P(F and E ) / P(E )

Then

P(F and E ) = P(F | E ) P(E ) = 0.5 • 0.2 = 0.1

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
