Ram and Ramesh appeared in an interview for two vacancies

Ram and Ramesh appeared in an interview for two vacancies in the same department. The probability of Ram's selection is 1/6 and that of Ramesh is 1/8. What is the probability that only one of them will be selected?

P (Ram) = 1/6; p(Ramesh) = 1/8 p(only at) = p (Ram) × p (not ramesh) + p(Ramesh) × p(n₀ × R_am)

=	1	+	7	+	1	×	5
	6		8		8		6

⇒	12	=	1
