Question

when number is taken from 1 to 15, the probability that it is neither prime nor composit, is​

Answer 1

Answer:

1/15

Step-by-step explanation:

because all the numbers except 1 are either prime or composite numbers

No. of favourable outcomes/ Total possible outcomes =

1/15

Answer 2

Answer: $\frac{1}{15}$

Step-by-step explanation:

❍ Given :-

• Total outcomes = 15

❍ Solution :-

We know that,

⇝ 1 is the only number which is neither prime nor composite.

Hence number of favorable outcomes will be only one.

$\boxed {\tt \small{Probaility = \dfrac{Number \: of \: favourable \: outcomes}{Total \: of \: outcomes}}}$

$\sf→Probability = \dfrac{1}{15}$

Hence the probability when number is taken from 1 to 15 is $\frac{1}{15}$.
