D. 9. (Go to Solution) Find the probability that both marbles are red. A. B. C. D. 10. (Go to Solution) Approximately 70% of U. S. adults had at least one pet as a child. We randomly survey 60 U. S. adults. We are interested in the number that had at least one pet as a child. The probability that at least 3 adults had at least one pet as a child means: A. P(X = 0) + P(X = 1) + P(X = 2) B. P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) C. P(X = 4) + P(X = 5) + P(X = 6) + ... + P(X = 60) D. P(X = 3) + P(X = 4) + P(X = 5) + ...
