At a middle school science fair, all the science fair projects used mathematics, but only30% of the projects display the mean or the median. 27% of all the science fairprojects display the mean and 16% of all the science fair projects display the median.1. Apply the addition rule, P(mean or median) = P(mean) + P(median) - P(mean andmedian), to find the probability that a randomly selected project at this science fairdisplays the mean and the median. Explain or show your reasoning.2. Use a Venn diagram to represent the percentage of science fair projects thatdisplay the mean, median, or both the mean and the median

We have given that P( mean or median ) = 30% = 0.30 P( median ) = 16% = 0.16 P( mean ) = 27% = 0.27

Answered: 1. Apply the addition rule, P(mean or…
