Balls numbered from 1 to 38 are placed in a contianer and stirred. if one is drawn at random what is the probability that the number is a prime number?

The primes in the range 1–38 are ...

... 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37

There are 12 of them, so the probability of drawing a prime is

... 12/38 = 6/19

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question
