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

- Can someone help me with this please?arrow_forwardMariela is in her classroom and looking out of a window at a tree, which is 20 feet away. Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward1arrow_forward
