Let `alpha_1` be the total number of ways in which the committee can be formed such that the committee has 5 members, having exactly 3 boys and 2 girls. (ii) Let `alpha_2` be the total number of ways in which the committee can be formed such that the committee has at least 2 members, and having an equal number of boys and girls. (iii) Let `alpha_3` be the total number of ways in which the committee can be formed such that the committee has 5 members, at least 2 of them being girls. (iv) Let `alpha_4` be the total number of ways in which the committee can be formed such that the committee has 4 members, having at least 2 girls and such that both `M_1` and `G_1` are NOT in the committee together. LIST-I LIST-II P. The value of `alpha_1` is 1. `136` Q. The value of `alpha_2` is 2. `189` R. The value of `alpha_3` is 3. `192` S. The value of `alpha_4` is 4. `200` 5. `381` 6. `461` The correct option is: `Prarr4; Qrarr6; Rrarr2; Srarr1` (b) `Prarr1;Qrarr4; Rrarr2; Srarr3` (c) `Prarr4; Qrarr6; Rrarr5; Srarr2` (d) `Prarr4; Qrarr2; Rrarr3; Srarr1`
