Answer:
55/2574 ≈ 2.18%
Step-by-step explanation:
There are a total of 13 people on the council.
The probability that the first person is a Democrat is 8/13.
The probability that the second person is a Democrat is 7/12.
The probability that the third person is a Republican is 5/11.
The probability that the fourth person is a Republican is 4/10.
The probability that the fifth person is a Republican is 3/9.
The total probability is:
P = (8/13) (7/12) (5/11) (4/10) (3/9)
P = 56/2574
P ≈ 0.0218
There is a 2.18% probability of selecting two Democrats and three Republicans.
Sin(90-A) = cos A
cos(90-A) = sin A
Therefore,
tan(90-A) = sin(90-A)/cos(90-A) = (cos A)/(sin A) = 1/(tan A)
Answer:
You are setting up chairs for the band concert tonight, the band conductor tells you to set up four rows with nine chairs each. How many chairs will there be all together.
to solve:
