Answer:
1. A = 3/12
B= 4/12
C = 5/12
2......
3. Randy
Step-by-step explanation:
3+4+5 = 12
therefore there are 12 letters in the box
we can say that there are 3/12 A's in the box and do the same for the remaining letters
question two does not make sense
3. the person who has the lowest fraction in value which is A
Part B seems to be missing, but I think I have enough information to be able to answer.
Let's say we had two numbers x and y. Let x be rational and y be irrational.
If x is some nonzero number, then x*y is irrational. The proof for this is a bit lengthy so I'll leave it out.
For instance,
x = 2 is rational, y = sqrt(3) is irrational, x*y = 2*sqrt(3) is irrational.
------------------
If we made x = 0, then
x*y = 0*y = 0
This is true for any value of y that we want. The y value doesnt even have to be irrational. It can be any real number.
------------------
So the distinction is that if x = 0, then x*y = 0 is rational since 0 is rational. Otherwise, x*y is irrational.
Answer:
Probability = the number of ways of achieving success. the total number of possible outcomes. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail).
