Hi,
*Note: Using The binomial theorem lets us obtain the probability of an event or a number of events
P=+%28n%21%2Fr%21%28n-r%29%21%29p%5Er%2A%281-p%29%5E%28n-r%29
.
For 8 successes out of 8 selected: P+=+1%2A%28.75%5E8%29%2A%28.25%5E0%29+=+.10
10% chance of all 8 randomly selected graduates all finding jobs in their chosen field within a year of graduating
