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
The best deal for a package of soap would be (a).
The mean is 5.5! All you do is add up all the numbers then divide by how many numbers there are
I think m = 3. Because on the other all sides are equal. (12) and the other side is 3 so that most likely means all sides are 3. Hope this helps
Answer:
m = -1
Step-by-step explanation:
11m - 4 = -15 Add 4 to both sides
11m = -11 Divide both sides by 11
m = -1
