two balls are drawn at random from an urn containing six white and nine red balls. Recall, the equation for C(n,r) given below c(n,r)=n(n-1)(n-2)...(n-r+1)/r! a)use combinations to compute the probability that both balls are white. (type integer or decimal with two decimal places) b) compute the probability that both balls are red. (type integer or decimal with two decimal places)
