You have the numbers 1–24 written on slips of paper. If you choose one slip at random, what is the probability that you will NOT select a number which is divisible by 3?

So, the probability is P=2/3.

Step-by-step explanation:

We have the numbers 1–24 written on slips of paper.  If you choose one slip at random, what is the probability that you will NOT select a number which is divisible by 3.

It actually means: How likely are we to choose a number not divisible by 3.

In integers 1 to 24, the following numbers are divisible by 3:

3, 6, 9, 12, 15, 18, 21, 24

So there are 8 numbers in total.  

So, 16 numbers not divisible by 3.

We get

So, the probability is P=2/3.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

26?
