If you take the square root of 52 and then divide by two you get about 3.6. You take i and multiply it by that and you get 4. Then divide 40 by 2 to get 20. Then you subtract the inverse of the mulltiagion thereom to get 4.
4+4=8
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
in mix number, the answer will be
if you need in decimal form than the answer in going to be
