1/8 or 1/6
which is greater
1) Lets make the fraction into a percent
1/8 ⇒ 1 ÷ 8 = 0.125
0.125 x 100 = 12.5%
1/6 ⇒ 1 ÷ 6 = 0.16....
0.16.. x 100 = 16.6.. = 16.7%
1/8 is bigger since it is closer to 0.
Hope this helps
5:9
You need to find the greatest common factor and divide each side by it.
In this case it is 10... 50/10 = 5 90/10 = 9
So 50:90 = 5:9
Answer: C
Explanation: they will never touch
Answers:
- P(A or B) <u>not</u> mutually exclusive
- P(A and B) <u>not</u> independent (aka dependent)
- P(A and B) independent
- P(A or B) mutually exclusive
- P(A | B)
=============================================
Explanation:
The formula we use for "or" cases is
P(A or B) = P(A) + P(B) - P(A and B)
If events A and B are mutually exclusive, then we ignore the P(A and B) part since that is 0. Mutually exclusive events cannot occur simultaneously, which is why we have that 0.
-----------
For "and" cases, we have two basic flavors
P(A and B) = P(A)*P(B | A)
P(A and B) = P(B)*P(A | B)
We go with the first case for problem 2. These formulas apply if A and B are not independent.
If they are independent, then
P(A and B) = P(A)*P(B)
-----------
Start with the equation P(A and B) = P(B)*P(A | B) and divide both sides by P(B).
You'll end up with
P(A | B) = P(A and B)/P(B)
which is a conditional probability.
C. 56 + x =72 because the team player already scored 56 points you would need to add an unknown amount of points in this case x to find out how many points you need in order to reach 72 points and if you are curious how many points you need in order to get to 72 you need 16 points.
