- Spinner A and B shown in the figure are spun at the same time. (a) Are the events "spinner A stops on red” and “spinner B stops on yellow” independent? (b) Find the probability that spinner A stop on red and spinner B stops on yellow.arrow_forwardLet E and F be events in a sample space S. aThe probability of E or F occurring is P(EF)= _________. bIf the events E and F have no outcome in common that is, the intersection of E and F is empty, then the events are called ___________ ____________. So in drawing a card from a deck, the event E, getting a heart, and the event F, getting a spade, are ____________ ___________. cIf E and F are mutually exclusive, then the probability of E or F is P(EF)= _________.arrow_forwardLet E and F be events in a sample space S. aThe probability of E and F occurring is P(EF)=______________. bIf the occurrence of E does not affect the probability of the occurrence F, then the events are called ____________. So in tossing a coin twice, the event E, getting heads on the first toss, and the event F, getting heads on the second toss, are ____________. cIf E and F are independent events, then the probability of E and F is P(EF)=________.arrow_forward
