Vedclass · Answer

(D) Total number of socks $= 5 + 4 = 9$.The total number of ways to select $2$ socks out of $9$ is given by $^9C_2 = \frac{9 	imes 8}{2 	imes 1} = 36$.The number of ways to select $2$ brown socks is $^5C_2 = \frac{5 	imes 4}{2 	imes 1} = 10$.The number of ways to select $2$ white socks is $^4C_2 = \frac{4 	imes 3}{2 	imes 1} = 6$.The probability that both socks are of the same colour is $P(	ext{Both brown or both white}) = \frac{^5C_2 + ^4C_2}{^9C_2} = \frac{10 + 6}{36} = \frac{16}{36}$.To match the given options,we multiply the numerator and denominator by $3$: $\frac{16 	imes 3}{36 	imes 3} = \frac{48}{108}$.
