Question

A drawer contains 12 brown socks, 8 white socks, and 2 blue socks. One sock is selected at random.

What is the probability that the sock is blue, given that it is not brown?

A. 1/4
B. 1/5
C. 1/10
D. 1/11

Answer 1

Okay so,
Probablity's formula is :
Favourable Items
===========
Total Items


We know that It can't be brown.

Answer 2

The probability that the sock is blue when selected at random is

2 <--blue, favourable
10<- white+blue =total.

Answer 3

So,
\[\frac{ 2 }{ 10 } =\frac{ 1 }{ 5 }\]
