Answer 26

Your Welcome! Feel free to give me a medal and follow me!

Answer 27

The probability is 30%. I started of by using the fraction 3/5 which is 6% and then 2/4 which is 50%.
Then i multiplied 3/5 and 2/4 which was .3 and then i changed it to a percentage which is 30%

Answer 28

thats what i got.

Answer 29

i meant off not of btw

Answer 30

Looks good, but you might want to add why we used the fractions 2/4 and 3/5.
Add that it is Probability= Favorable Cases/Possible Cases
