Answer:
2.10% probability that the group will consist of all Republicans.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the order in which the members are selected is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
4 republicans from a set of 6.
Total outcomes:
4 members from a set of 6 + 7 = 13.
Probability:
2.10% probability that the group will consist of all Republicans.
Answer:
16/24
Step-by-step explanation:
the answer is 32 because 32×(1/4) or 32/4 is 8 there for 8 is a fourth of 32
Answer:
4/6
Step-by-step explanation:
Answer:
1/9
Step-by-step explanation:
a - b = 2
27^(1/3b)/9^(1/2a)
so...b = a - 2
27^( (1/3) b ) / 9^((1/2) a )
= (3^3)(1/3b) over (3^2)^(1/2a)
= 3^b over 3^a = 3^ (b - a) = 3^(-2) = 1/9
--------------
9^(1/2b)/3^a = (9^(1/2))^b / 3^a = 3^b / 3^a = 3^(b -a) = 3^-2 = 1/9
