Step-by-step explanation:

Composite numbers are those which have

3

or more factors:

Prime numbers are those which have exactly

2

factors:

There are more composite numbers than prime numbers, (can you explain why this is so?)

So it will be easier to count the prime numbers and subtract them.

There are

50

numbers FROM

1

to

50

Therefore there are

48

numbers BETWEEN

1

and

50

. which are excluded.

There are

15

prime numbers less than

50

, which are:
