The probability event is
Explanation of Solution
Given information:
Event:
Pilar is playing a board game with eight diffreent categories, each with questions that must be answered correctly in otder to win.
Calculation:
Pilar is playing a board game with eight diffreent categories, each with questions that must be answered correctly in otder to win. To simulate the outcomes, make a spinner with eight equal segments that represent probability that the probability is chosen.
Spin the spinner
The frequency of outcomes will vary between sets of
Outcome | Frequency |

Now, divide each frequency in the frequency table to get the probabilities for each outcome.

Make a probability histogram by charting probability on the vertical axis and outcomes on the horizontal axis.
Hence, the probability that a certain one of the eight categories is necessary is selected is about
Therefore, the probability event is
