Answer:
The answer is 15 people.
Step-by-step explanation:
If one fifth is bringing candy and three fifths is bringing dessert than that already four fifths of the people who aren't bringing punch so one fifth of the people are bringing punch so one fifth of 75 is equal to 15
Probability is calculated by comparing the odds to a certain event occurring to the number of possible events.
P=

For example, take a six-sided dice number 1-6 on each side. The probability of rolling a 4 would be1 in 6 or 1/6. This is because of the six possible outcomes, rolling a 4 is only one of them.
P(4)=1/6
Now take the same dice. The probability of rolling an even number is 3/6. To see why, lets look at the total possible outcomes:
1
23
45
6
Of the 6 possibilities, 3 are even numbers.
P(even)=3/6 or 1/2
2/25 will be the simplest form
