Suppose that E and F are two events and that P(E)=.8 and P(F/E)=.6 What is P(E and F)?​
jeka57 [31]

Lets turn E into x and F into y.

We already know that x is 0.8. And if y/x = 0.6, we have to figure that out.

y/x = 0.6

y/0.8 = 0.6

Multiply by 8 to get y = 0.48.

So we have to find P(xy)

So if we know that x = 0.8 and y = 0.48 then all we have to do is multiply 0.48 and 0.8.

0.48 * 0.8 = 0.384

P(E and F) is 0.384.
