Answer:
The probability that a student is taking calculus given that he or she is taking statistics is = 0.26
Step-by-step explanation:
the probability that a student is taking calculus given that he or she is taking statistics.
Let C = Calculus
S = Statistics
We solve this above Question nursing the formula;
P ( C ∪ S) = P(C) + P ( S ) - P ( C ∩ S)
From the question,
P(C) = 0.10
P( S ) = 0.18
P ( C ∩ S) = 0.02
P ( C ∪ S) = ???
P ( C ∪ S) = 0.10 + 0.18 - 0.02
= 0.28 - 0.02
= 0.26
Answer:
The survey shows that 20% of the individuals were satisfied with the car.
Step-by-step explanation:
- We are given that 2,300 people were surveyed.
- We are also given that 460 of those individuals would buy that car again.
- We need to find the percentage of individuals that were satisfied with the car.
When we need to find the percentage of a population, we can use the following formula:
We need to identify the part and the whole in this problem.
We are given that 2,300 people are surveyed, so this is the <u>whole</u> portion.
We are also given that 460 were satisfied, so this is the <u>part</u> portion.
Therefore, we can set up our fraction.
Now, let's solve the percentage.

Therefore, of those surveyed, 20% of the individuals were satisfied with the car.
