hello everyone

I'm new in this fórum and I have this problem.

I need to now the value of P(Y=MAN|X=80kg)

I do this but i don now it is correct

P(Y | X=80) = P(X=80 | Y) x P(Y) = 0.20 x 0.666 = 0.666
P(X) 0.20
is that correct?

After taking 1000 measurements, it is known that there are 20 men who weigh 80kg and 10 women who weigh 80kg.
How much is P (Y = Man | X = 80kg) worth?
