It is 2 4/5, 2 4/5 is 2.8, 4/5 is greater than 3/4
The "one head and one tail" would be my best guess because you get one of each outcome, whereas the other two outcomes are two of the same outcome.
On your calculator, use the normalcdf() function, enter the Lower Limit, Upper Limit, Mean, and Standard deviation.
The mean and standard deviation are given to you. You want to find "less than 13.5 seconds", meaning that 13.5 is the maximum "Upper Limit" and 0 would be the Lower Limit because we can pretend 0 second is the minimum. Don't worry about negatives, in this scenario, values like "-5 seconds" are impossible.
Enter normalcdf(0, 13.5, 13.56, 2.24) in a calculator and the output result is the answer.
93, 94, 95, 89, 85, 82, 87, 85, 84, 80, 78, 78, 84, 87, 90.

Answer:
86 is the mean and the median is 85
Step-by-step explanation:
To calculate the mean all u gotta do is add all the numbers then divide by how many numbers there is and to calculate the median all u gotta do is put them in order 78-95 then mark 1 on each side til you reach the middle and the number in the middle is the answer.
