Three boys and two girls stand in a queue.The probability,that the number of boys ahead is at least one more than the number of girls ahead of her,is (A) (1)/(2)(B)(1)/(3)(C)(2)/(3)(D)(3)/(4)

Let n be the number of ways in which 5 boys and 5 girls can stand in a queue in such a way that all the girls stand consecutively in the queue.Let m be the number of ways in which 5 boys and 5 girls can stand in a queue in such a way that exactly four girls stand consecutively in the queue.Then the value of m/n is
