Just add 70 and 30 together and then subtract it from 180
70+30+x=180 100=180 subtract 100 from 180 and x=80 and to check this just add 70+30+80=180 it checks out
Hope this helps have a nice day
The probability of the first pick to be a boy is 10/25.
Let S be the sample space and E be the event of selecting 1 girl and 2 boys.
n(S)=number of ways selecting students of 25.
=²⁵C₃
=25·24·23/3·2·1
=2300
n(E)=(¹⁰C₁·¹⁵C₂)
=[10·(15·14)/2·1
=10500
P(E)=n(E)/n(S)=1050/2300=21/46
