This is a question for a statistics assignment. We are uncertain of exactly how to get the answer. We have two different answers and are looking for help as to how to get the answer. Thank you.

60/100 passed the first and 40/100 of 60/100 passed both, so the equation is probably 40/100*60/100

40/100*60/100

2/5*3/5

6/25

6/25 or 24% who passed the first passed the second.
