To calculate the probability of selecting a certain number of white balls and red balls from the urn, we need to know the total number of white balls and red balls and the number of balls Juan is picking.
Let's assume that the urn contains X white balls and Y red balls.
The probability of selecting W white balls and R red balls from the urn when Juan picks N balls can be calculated using the formula:
P(W, R) = (C(X, W) * C(Y, R)) / C(X+Y, N)
Where C(n, r) is the number of combinations of n items taken r at a time, given by the formula:
C(n, r) = n! / (r! * (n-r)!)
Now, let's assume Juan is picking W white balls and R red balls from the urn when the total number of balls he is picking is N. We need to calculate:
P(W, R) = (C(X, W) * C(Y, R)) / C(X+Y, N)
Since we don't have the specific values of X, Y, W, R, and N, we cannot provide a specific result. However, you can substitute the values of X, Y, W, R, and N into the formula and calculate the probability accordingly.
