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: 122
Explanation: 250 - 5 = 245
(The 5 comes from the president, Vice President, two volunteers, and guess speaker)
245/2 = 122.5
Half a couple cannot attend so the answer would be 122 couples can attend
Answer:
Answer is 6 the value of x is 6
In the given figure above, we can use the formula for tangent-tangent angle. This is under the type of angle whose vertex is outside the circle and its sides intersects the circle.
Applying the tangent-tangent angle formula:
m∠APB =
(ALB - AB)
m∠APB = angle of the vertex
ALB = measure of arc ALB
AB = measure of arc AB
we all know that the total measure of arc is equal to 360, hence, ALB + AB = 360
let: x = measure of arc AB
360 - x = measure of arc ALB
substitute:
78 =
{(360 - x) - x}
78 =
(360 - 2x)
78 = 180 - x ⇒ simplifying further by dividing both 360 and -2x by 2
x = 180 - 78 ⇒ combining like terms
x = 102
arc AB = 102 ⇒ Answer
