Answer:

3.  83%, or A

Step-by-step explanation:

First you have to create the variables.

If you need to find the probablility of two items, then you first add them.

11+14 = 25.

Now, you add all the numbers.

22+14+5 = 30.

Using that, make a fraction then simplify.

25/30 = 5/6

4: D

Using the same process, add everything but the green balls.

11+5 = 17.

Now add them all up.

11+14+5 = 30

Form a fraction, then simplify.

17/30 = approximately 8/15

Answer:

Question 3: 5/6

Question 4: 8/15

Step-by-step explanation:

Yellow = y

Green = g

Red = r

Question 3) Hat:

5 red balls, 14 green balls, and 11 yellow balls

What is the probability that a yellow or green ball is chosen?

Write an equation:

y + g / y + g + r

Substitute

11 + 14 / 11 + 14 + 5

Add/Simplify

25/30

Divide both the numerator and denominator by 5 to simplify

25 ÷ 5 / 30 ÷ 5

5/6

Question 4) Bag:

5 red balls, 14 green balls, and 11 yellow balls

What is the probability that John does not choose a green ball?

Write an equation

y + r / y + r + g

Substitute

11 + 5 / 11 + 5 + 14

16/30

Divide both the numerator and denominator by 2

16 ÷ 2 / 30 ÷ 2

8/15

Hope this helps :)
