Using the probability concept, we have that:
- There is a 0.6286 = 62.86% probability that a randomly selected person is female or prefers mint chocolate chip.
- There is a 0.3714 = 37.14% probability that a randomly selected person prefers cookie and cream or vanilla.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 35 people, out of which 17 are female and 5 are male that prefer mint chocolate chip, hence:
p = (17 + 5)/35 = 22/35 = 0.6286.
There is a 0.6286 = 62.86% probability that a randomly selected person is female or prefers mint chocolate chip.
Out of the same 35 people, 11 people prefer cookie and cream and 2 people prefer vanilla, hence:
p = (11 + 2)/35 = 13/35 = 0.3714
There is a 0.3714 = 37.14% probability that a randomly selected person prefers cookie and cream or vanilla.

Answer:
The number of $100 bills was 27.
The number of $50 bills was 69.
The number of $20 bills was 189.
Step-by-step explanation:
Let x be the number of $20 bills, y the number of $50 bills, and z the number of $100 bills.
Since there are three unknown values, we need three equations to solve the problem, all of them can be extracted from the question itself, two as the ratios between different bills and the last one as the sum of the total value of the money :
Substituting the first equations into the last, it is possible to find the value for z:
Knowing that there were 27 $100 bills, we can go back to the first two equations to find x and y:
The number of $100 bills was 27.
The number of $50 bills was 69.
The number of $20 bills was 189.
Answer:
Step-by-step explanation:
You need to find out what x and y is first then you can solve it
Polygons, Number of sides, Measure is angles, and angle sums
