Question

If an integer from 3 through 14 is chosen at random, what is the

Answer 1

Answer:$\frac{7}{12}$

Step-by-step explanation:

Given

There are integer between 3 and 14 available to be chosen (total 12 integers)

Prime integers among them

3,5,7,11,13 i.e. total of 5 prime integers

So the probability that the number chosen is not Prime

$=1-P\text{(no is prime)}$

$=1-\frac{5}{12}$

$=\frac{12-5}{12}$

$=\frac{7}{12}$
