To calculate the mean, you have to add and divide all the numbers

the numbers 48,72,76,61 and 68 add up to 325

325 divided by 5 = 65.

The mean average pass mark is 60 on 6 exams. She needs to get a pass mark of at least 40 bare minimum on her last exam to pass the test. this is because 325 + 40 = 365. 365 divided by 6 = 60.83333..
