Answer 1

Answer:

4 marbles take out to be sure that at least 2 of 1 color among the marbles picked out.

Step-by-step explanation:

Given:

Total number of balls in box = 16 balls

Number of green color ball = 4

Number of blue color ball = 4

Number of yellow color ball = 4

Number of red color ball = 4

To find: Number of marbles take out to be sure that at least 2 of 1 color among the marbles picked out.

We have 4 types of colors.

So if we take 1 marble out then we only have marble of 1 color.

So if we take 2 marble out then we only have marble of 2 color.

So if we take 3 marble out then we only have marble of 3 color.

So if we take 4 marble out then we only have marble of 4 color.

So if we take 5 marble out then we have marble of 4 color in which 2 marble are of 1 color.

Therefore, 4 marbles take out to be sure that at least 2 of 1 color among the marbles picked out.
