Answer to Question #481 in Statistics and Probability for Daniel
What is more likely: get a coat at least once or get tails twice while throwing a coin twice?
Here are the possible variants (1st throwing, 2nd throwing): (coat, coat), (coat, tails), (tails, coat), (tails, tails). Thus, the probability to get a coat is P(coat)=3/4 and the probability to get tails twice is P(tales)=1/4. Thus, it’s more likely to get a coat at least once.
