This can be done easily if you choose a different probability.
Find the chance that none of the 5 graduates find a job.
For one student that is 100%-62%=38%
This has to happen for all 5 students, that is P=(0,38)^5=0,008 (rounded)
This is the chance that none of the 5 students finds a job. All of the above cases at least one finds a job.
That is 1-0,008=0,992 (rounded)
If he swan the length and the width of the pool it would be 21 x28 = 588 sq ft.
by swimming the length and the diagonal of the pool (25 ft) found that by using the pythagorean therom so now you are multiplying 21 x 25 = 525
588-525= 63 ft he is saving
