At a high school, 40% of the students are in a sport. 65% are in a club. What is the probability that a student selected at a random participates in a sport? In a club? IS the probability of both occurring more or less likely than either one occurring?
A deck of cards has 52 cards. 13 each of 4 different suits. The hearts and diamonds are red and the spades and clubs are black. What is the probability of drawing a heart? If you draw a heart and not replace, what is the probability of drawing it again? If you draw 3 times, replacing each card, what is the probability of drawing 3 hearts? Construct tree diagrams of each the experiments.
Answers would work but what I need most is how to solve them. Thanks!
