For two events X and Y in S, Pr(X) = 0.3, Pr(Y) = 0.4, and Pr(X or Y) = 0.6. Given X has occurred, what is the probability of Y? i.e., Pr(Y|X)?
Added by Jose G.
Step 1
Step 1: The probability of X or Y occurring can be calculated using the formula: Pr(X or Y) = Pr(X) + Pr(Y) - Pr(X and Y) Show more…

The events X and Y are mutually exclusive. Suppose P(X) .05 and P(Y) .02. What is the probability of either X or Y occurring? What is the probability that neither X nor Y will happen?
The events $X$ and $Y$ are mutually exclusive. Suppose $P(X)=.05$ and $P(Y)=.02$. What is the probability of either $X$ or $Y$ occurring? What is the probability that neither $X$ nor $Y$ will happen?
