There are pencils in the box: 10 red ones, 8 blue, 8 green, 4 yellow. Let us take, with eyes closed, some number of pencils from the box. What is the least number of pencils we have to take in order to ensure that we get at least 4 pencils of the same color?

Step-by-step explanation:

GIVEN: There are pencils in the box: red ones, blue, green, yellow. Let us take, with eyes closed, some number of pencils from the box.

TO FIND: What is the least number of pencils we have to take in order to ensure that we get at least pencils of the same color.

SOLUTION:

Total number of red pencils

Total number of blue pencils

Total number of green pencils

Total number of yellow pencils

if we pick pencil, there can be pencil of each color

Least number of pencils we have to take in order to ensure that we get at least pencils of the same color is .

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

i think 1: 2
