Correct Choose the correct choice from the following options.
A) 1/35 B) 1/34 C) 1/68 D) 1/17 E) 1/18
Total number of possible arrangements for 4 boys and 3 girls in a queue = 7!   When they occupy alternate position the arrangement would be like:   B G B G B G B   Thus, total number of possible arrangements for boys = (4 x 3 x 2)   Total number of possible arrangements for girls = (3 x 2)   Required probability = (4 x 3 x 2 x 3 x 2)/7!   = 1/35   1/35NSWER:1/35
