There are 10 juice boxes in the cooler altogether.
2 of them are grape.

The first time Jill pulls one out with her eyes closed,
the probability that it's a grape is

2 / 10 .

If that try is successful, then there are 9 boxes left in the cooler,
and one of them is grape.

If she already has one grape, and reaches in again with her eyes
closed, the probability of pulling out the second grape is

1 / 9 .

The probability of both events happening in two tries is

(2/10) x (1/9) = 2/90 = 1/45 = (2 and 2/9) percent .

How do you find the mean absolute deviation MAD

lawyer [7]

Answer:

Most of the time you can go on a website that can cauculate it.

Step-by-step explanation:

How to cauculate the MAD:

Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. Finally, round to the nearest tenth.

one teacher want to give each student 4/5 of a slice of pizza, if the teacher has 4 slices of pizza, then how many students will

GuDViN [60]

Answer:

The answer is 5 students.

Step-by-step explanation:

This problem is a division problem.

To solve, divide 4 by 4/5.

There is a strategy for this- Keep, Change, Flip.

Keep the dividend like it is, which is 4 or 4/1.

Change the division to multiplication.

And flip the divisor- 4/5 to 5/4.

When you multiply, you should get 20/4.

Simplify by dividing 20 by 4.

20 divided by 4 is 5.

So the answer is 5 students
