and

Upper P left parenthesis F|E right parenthesisP(F|E)equals=0.2

What is

Upper P left parenthesis Upper E and Upper F right parenthesisP(E and F)​?

Answer 1

Given that,

E and F are two events and P(E) = 0.8 and P(F|E) = 0.2

[ Formula:-

]

So applying formula (i) we get,

Now we put the given value and we get,

[ Applying formula (ii) ]

Answer:- Our required probability is,
