No, there are not two different answers. The probability that, of 5 people, they are as said, is the product of all 5 fractions.

## is this right?

What is the probability that if 5 students are randomly selected, without replacements, the first 3 are taking less than 8 units and the last two are taking at least 8 units.

I got 1395/2461 x 1394/2460 x 1393/2459 AND FOR the last 2 taking at least 8 units, 1066/2458 x 1065/2457.

Did I do this right?
