Answer:
(I suppose that we want to find the probability of first randomly drawing a red checker and after that randomly drawing a black checker)
We know that we have:
12 red checkers
12 black checkers.
A total of 24 checkers.
All of them are in a bag, and all of them have the same probability of being drawn.
Then the probability of randomly drawing a red checkers is equal to the quotient between the number of red checkers (12) and the total number of checkers (24)
p = 12/24 = 1/2
And the probability of now drawing a black checkers is calculated in the same way, as the quotient between the number of black checkers (12) and the total number of checkers (23 this time, because we have already drawn one)
q = 12/23
The joint probability is equal to the product between the two individual probabilities:
P = p*q = (1/2)*(12/23) = 0.261

Answer:
The quotient of any nonzero integers, a and b, is always a rational number.
Step-by-step explanation:
We know that a rational number is any number that can be written in the
form of
, where q is not equal to zero.
- p/q is basically the quotient of integers (non-zero).
p and q integers mean they are rational number. As the quotient is generated by the division of these two numbers, and q is not equal to zero.
- As q can be equal to 1, so every integer is a rational number.
Therefore, the quotient of any nonzero integers, a and b, is always a rational number.
10 is the least common denominator
5, 11 and 2 are all prime numbers which add together to create 18.
5+11=16+2=18
