Answer:
Option B is correct.
Step-by-step explanation:
B- Spinning “back 2 spaces” on a spinner is a simple event. The probability that it will get 2 spaces back from where it started first is a single event.
A involves probability of landing 2 spaces back along with the probability of drawing a blue or red marble from a box. This is compound event.
C also involves 2 probabilities.The probability of getting an odd number on a die plus the probability of getting tails on the toss of a coin.
D involves 5 probabilities with one probability for each toss.
Therefore, option B is correct.
