37. Socks. In your sock drawer you have 4 blue socks, 5 grey socks, and 3 black ones. Half asleep one morning, you grab 2 socks
mihalych1998 [28]

Answer:

a) \frac{1}{22}

b) \frac{7}{22}

c) \frac{5}{11}

d) \frac{35}{66}

Step-by-step explanation:

Given,

Number of blue socks = 4,

Grey socks = 5,

Black socks = 3,

Total socks = 4 + 5 + 3 = 12,

Ways of choosing any 2 socks = ^{12}C_2

=\frac{12!}{2!10!}

=\frac{12\times 11}{2}

=6\times 11

= 66,

a) Ways of choosing 2 blue socks = ^3C_2

= 3,

Since, \text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}

Thus, the probability of selecting 2 blue socks = \frac{3}{66}=\frac{1}{22}

b) Ways of choosing 2 shocks, non of them are grey socks = ^7C_2

=\frac{7!}{2!5!}

=7\times 3

=21

Thus, the probability of selecting no grey socks = \frac{21}{66}

=\frac{7}{22}

c) ways of selecting atleast 1 black sock = ways of selecting 1 black sock + ways of selecting 2 black socks

=^3C_1\times ^9C_1+^3C_2

=3\times 9 + 3

=27 + 3

= 30,

Thus, the probability of selecting at least 1 black sock = \frac{30}{66}

=\frac{5}{11}

d) Ways of selecting a green sock = ^5C_1\times ^7C_1

= 35,

Thus, the probability of selecting a green sock = \frac{35}{66}
