Help with this I don't know how to solve., thanks

The right answer is the fourth one, 11,66.

Step-by-step explanation:

The correct option is (D) The number generator is not fair. In most of the experiments, considerably less than 40% of the selected are green.

Step-by-step explanation:

The correct option is (d) The number generator is not fair. In most of the experiments, considerably less than 40% of the selected are green.

Step-by-step explanation:

Solution

In this example,40% of the beads are green, the number generator is not fair. so the option B is ruled out.

Also, the option C is ruled out

Now,

If we Consider the option A, The sum of the total number of green beads in all experiments

Which is,

12*4 = 48. But the total number of green beads is only 12. That's why, even when the graph is skewed, the generator is not fair. So, the option A is also ruled out.

Thus,  

As the number generator is not fair, and in most experiments, less than 4 green beads are selected. the option D is the correct option.
