Answer:
The answer is 1/3 or 0.33
Step-by-step explanation:
Let's consider the following ocurrences:
A: A person has a MasterCard
B: A person has an American Express
The data says:
P(A∩B) = 0.2
P(A without B) = 0.4
P(B without A) = 0.1
Then, P(A) = P(A∩B) +P(A without B) = 0.2+0.4 = 0.6
By conditional probability theory:
P (B/A) = P(A∩B) / P(A) = 0.2 / 0.6 = 1/3 = 0.33
Thus
P(B/A) = 1/3 = 0.33
Answer:
A= Yes
B= No
C= Yes
D= No
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
Create a ratio
3:8
Since the total(denominator) is 8.
We can find a ratio of 24 total students so,3:8.
3:8
_:24
You multiply 3 on each side.
8×3=24
3×3=9
180 - 46 - 24 = 110
d+ 80 = 110
d = 30
answer
d = 30
Answer:
D
