Answer 2

Let,

b= boy

g= girl

The conditions which may come__

(i) ggg

(ii) ggb

(iii) gbb

(iv) bbb

∴ Total number of outcome = 4

Number of favourable outcome = 3 (ggb,gbb,bbb)

∴ P (getting at least one boy ) = No. of favourable outcome/ No. of total outcome

                                               =  3/4

∴ The probability of getting at least one boy is 3/4.
