B. Tossing a coin 5 times and getting heads twice

Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! i think selection A would be a simple event.
A is one spin and the probability that it will land 2 spaces back from where it started would be a single event.
B involves 5 probabilities, one for each toss.
C involves 2 probabilities. the probability of getting an odd number on a die and the probability of getting tails on the toss of a coin.
D involves probability of landing 2 spaces back plus the probability of drawing a blue or red marble from a box.
A would be the single event.
B,C,D be compound events.
here's some words on single, compound, and complementary events that might be helpful for you to understand the difference.
