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.)

Question
Suppose that the joint
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.
