Answer to Question #16852 in Statistics and Probability for Estela
Nancy is throwing a standard six sided die. If she throws a 4 on her first throw, what is the probability that her next throw will NOT be. A 4?
Let X be the result of first throwing, and Y be the result of thesecodn throwing. We will assume that X and Y are independent, since we have no information. This means that p(X=k,Y=m) = p(X=k) * p(Y=m)
Since die is standard six sided, p(X=k) = p(Y=m) = 1/6.
