There are 30 socks in a drawer. 60% of the socks are red and the rest are blue. What is the minimum number of socks that must be taken from the drawer without looking in order to be certain that atleast two blue socks have been chosen? Choose the correct choice from the following options
A) 23  B) 37  C) 97  D) 20  E) 21
Explanation:   Number of red socks = 30 × 60% = 18   If you draw out 18 socks there's a possibility that all of them are red   If you draw out 19 socks one of them has to be a blue one   And if u draw 20 socks then definitely 2 of them are blue socks   So the answer is 20.   Answer:20
