Question

A bag contains 64 balls of eight different colours. There are eight of each colour (including red). What is the least number you would have to pick, without looking, to be sure of selecting 3 red balls? *

Answer 1

HEY MATE HERE IS YOUR ANSWER--

ANSWER IS 59

The first 56 balls could be of all colours except red. This would leave 8 balls, all of which are red, so any three chosen would be red.

Answer 2

Answer: There are 59 least number of balls that he would have to pick.

Step-by-step explanation:

Since we have given that

Total number of balls = 64

Number of balls of each colour = 8

Number of red balls are selected = 3

Remaining number of red balls = 8 - 3 = 5

so, the least number of balls he would be

$64-5\\\\=59\ balls$

Hence, there are 59 least number of balls that he would have to pick.
