Ajar contains black beads and green beads. forty percent of the beads in the jar are green. a number generator simulates randomly selecting 10 beads from the jar. the number generator is used 12 times and the number of green beads in each trial is shown in the dot plot. which description is correct about the number generator being fair or not?

Step-by-step explanation:

40% are green, and 10 beads are selected.  The expected number of green beads is 40% * 10 = 4.

Most of the 12 trials resulted in only 2 of the 10 beads being green.  So the number generator is not fair.  In most experiments, considerably less than 40% of the selected are green.

The one that says "The number generator is fair. The dot plot shows a distribution that is skewded right."

Step-by-step explanation:

It's fair because it's selected randomly.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

stops on an even number.
