Question

If there are 100 students in a Masters Degree program at OU, and there`s a 5% failure rate, how many students are left after 12 months?

Answer 1

5% fail
so 100-5=95% are left

percent means parts out of 100
95% of 100 is $\frac{95}{100}$ times 100=95

95 students are left assuming that the 5% that fail fail within 12 months
