This is statistics course and I need help with answering those questions.

D Question 39 1 pts Not considering births to more than one child, babies born at a particular hospital are independent events, with the probability that a baby is a boy is 0.49, and the probability that a baby is a girl is 0.51 percent. What is the probability that the next three babies born at the hospital are of the same sex? O 0.1327 O 0.2503 O 0.2499 O 0.0156 O 0.1177 10D Question 41 1 pts Eight friends decide to put together a flag football team in order to participate in their intramural league this summer. Based on past experiences with each of these friends, you have created a probability distribution of the number of friends who will actually show up to a game, where X is the number of friends who attend, and displayed the results below. X 2 3 5 6 17 8 P(X) 0.05 0.07 0.02 0.06 0.04 0.10 0.23 0.33 0.10 Suppose that each team in flag football must field a minimum of five players before they forfeit a game. What is the probability that your friends will have enough players to play?

If so, predict his score. If not, explain why. No, because it predicts a score of less than 200 points. No, because it predicts a score of more than 200 points. Yes, because it predicts a score of less than 100 points. Yes, because it predicts a score of more than 100 points. Yes, because the predicted score and the actual score are the same
