First off, rewrite all of the fractions so that they have a common denominator.  That's 2/12, 2/12, and 4/12.  Adding these together, we get 8/12.  That's the probability of getting an A, B, or C — but not a D.  The chance of getting a D is represented by the remaining 4/12 — or 1/3.  

TIn short, the chance of rolling D is exactly 1/3.

y-y1=m(x-x1)

so example
(1,2) and slope 3
y-2=3(x-1)



slope intercept
y=mx+b
m=slope
b=y intercept
if slope is 2 and y intercept is 3
y=2x+3

Hey Siri Council consist of eight Democrats and five Republicans if a committee of five people are selected find the probability
Flura [38]

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.
