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)
It is 2.69333333, to the nearest centimetre the answer is B) 3 cm per second
Seven, because 6.7 rounded to the nearest whole number is 7.
