Acombination lock uses 4 numbers each of which can be 0-36 if there are no restrictions on the numbers how many possible combinations are there?
if i could get an explanation on this it with the answer it would be appreciated

0-36 equals 37 total numbers.

So each number in the combination could be one of 37 numbers.

1st number can be 1 of 37

2nd number is 1 of 37

3rd number is 1 of 37

4th number is 1 of 37

Multiply each possibility by each other.

Total number of combinations is 37 x 37 x 37 x 37 = 1,874,161

36 girls

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
