Question 239099: question 1: A coin is biased to show 38% heads and 62% tails. The coin is tossed twice. What is the probability that the coin turns up tails on both tosses?
question 2: Find the probability.
If 81% of scheduled flights actually take place and cancellations are independent events, what is the probability that 3 separate flights will take place?
question 3: Suppose P(C) = .048, P(M ∩ C) = .044, and P(M C) = .524. Find the indicated probability.
P[(M ∩ C)']

You can put this solution on YOUR website! question 1: A coin is biased to show 38% heads and 62% tails. The coin is tossed twice. What is the probability that the coin turns up tails on both tosses?
Ans: (0.38)^2
--------------------------------
question 2: Find the probability.
If 81% of scheduled flights actually take place and cancellations are independent events, what is the probability that 3 separate flights will take place?
Ans: 0.81^3
--------------------------------
question 3: Suppose P(C) = .048, P(M ∩ C) = .044, and P(M C) = .524. Find the indicated probability.
P[(M ∩ C)']
If P(M and C) = 0.44, P[(M and C)'] = 0.56
