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

= 
Answer:

Step-by-step explanation:
3.242424.....
This number can be written as 3 + 0.242424....
We convert the decimal part into fraction
Let x= 0.242424......
Multiply both sides by 100
100x = 24.2424....
x= 0.2424.....
------------------------------------- (subtract it)
99x = 24
Divide both sides by 99
So x= 24/ 99
simplify the fraction

3.242424... can be written as 3 + 0.242424....
Replace the fraction for decimal
So final answer is 
Answer:
(C) 5/2
Step-by-step explanation:
=2(1/2)-3(1/2)+3(1)
=1-3/2+3
=(2-3+6)/2 ( taking LCM)
=5/2
