probability that a randomly chosen college student either has a job or lives on campus.
What is probability?
- Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true.
- The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
To find the probability that a randomly chosen college student either has a job or lives on campus:
Given: 85% of college students have a job, 54% live on campus, and 42% have a job and live on campus.
So, out of 100 students, 42 students either has a job or live on campus.
43 college students have a job and 12 live on campus.
So, 43 + 42 + 12 = 85 + 54 - 42
85 + 12 = 139 - 42
97 = 97
Therefore, probability that a randomly chosen college student either has a job or lives on campus.

Answer:
Question 9: 35 Question 10: 10
Step-by-step explanation:
Use BEDMAS (Brackets Exponents Division Multiplication Addition Subtraction).
Question 9:
Start with the brackets.
10 x 4 - (7 - 2)
= 10 x 4 - (5)
Then, multiply 10 and 4.
= 40 - 5
Solve the subtraction.
= 35
Question 10:
Start with the brackets.
1 - (2 - 3) + 8
= 1 - (-1) + 8
= 1 - - 1 + 8
(Two negatives = a positive)
= 1 + 1 + 8
Add the numbers.
= 10
