the probability of chosen a boy is : 12/20= 6/10= 3/5
therefore the probability is 3/5.

12(boys) divided by 20 (total)
12/20=.6
.6 X 100= 60% chance of getting a boy

the probability is
12 out of 20 = 12/20 = 0.6
which means that there is a 60% chance of choosing a boy.

There are a number of answers to this.
A quick answer would be 12/20 (or 60%).
However, if you were part of that class and were a girl then the chance would be 12/19 (unless you were silly enough to pick yourself).
If you were part of that class and were a boy then the chance would be 11/19, unless you were sensible enough to pick yourself then it would be 100%.
The above all assumed that you were picking blindly. If you used evidence e.g. looks, clothing or bodily appendages (or lack of) then the probability would be over 90% (at least).
