challenge. He biked for 65,68,45,48 AND 63 miles on the first five days. How many miles does he need to bike on the last day so that his average (mean) is 59 miles per day?

Question

I WANT YOU TO SOLVE FOR PROBABILITY

Answer 1

If the average was 59 miles per day after the 6th day, the sum of the miles he biked in those 6 days must have been 59*6 = 354. Figure out how many more miles he has to bike to have biked 354 miles.
