A spinner has six sections of equal shape and size. Each section is either black or white. The table shows the result of an experiment when the spinner was spun 90 times: Result of Spin Black White Number of Spins 72 18 Based on the data, which of the following best describes the experimental probability of the arrow landing on a black or white section of the spinner?
Ferredoxin:
The question is unclear. Are there any options? The scenario is mutually exclusive, as an event cannot occur simultaneously here. Thereafter, if we let P(A)=probability of black and P(B) as the probability of white, P(A∩B)=P(A)+P(B) and since those are the only 2 events, the probability is 1. If you are individually analyzing the probability, then the spinner is 4 times more likely to land on a black section than white.
