Question

Suppose that the joint probability distribution, f(x,y), of the discrete random variables X and Y is given by the following table

f(x,y) x=2 x=8
y=3 0.12 0.15
y=4 0.13 0.01
y=7 0.15 *

 

Given that X=2, find the contional probability that Y=4. (So, you need to find P(Y=4|X=2).)

Round your answer to a number  with two decimal digits after the decimal point. For example if your answer is 1/40, which is equal to 0.025, then you should enter 0.03.

(Do NOT use decimal comma; 0,03 would be wrong.)
