The Number of boys in the class is: 18
Let's call "g" to the number of girls in the class.
The problem says that there is "w" fewer boys than girls, so we have:
g-w=18
Then, the number of girls in the class is:
g=18+w
Let's call "x" to the total number of studens in the class:
x=g+18
When we substitute g=18+w into x=g+18, we obtain:
x= (18+w)+18
The total number of studens in the class is:
x=w+36
Answer:
The probability that the person will not be a senior
P(E⁻) = 1 - P(E)
= 
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given A high school club has 10 members who are seniors and 8 members who are juniors
n(S) = 10 + 8 = 18
If a member is randomly selected to be the club president
Let 'E' be the event that the person will be a senior
The probability that the person will be a senior
The probability that the person will not be a senior
P(E⁻) = 1 - P(E)
=
0.72 repeating is the sum of a geometric series with first term 0.72 and common factor 1/100. The sum is given by:
(first term) 0.72 0.72 72
--------------------------- = --------------- = ------------ = ------------
1 - common factor 1 - 1/100 99/100 99
This 72/99 can be reduced to 8/11.
0.72 repeating can be rewritten as the fraction 8/11.
