Answer 1

i'm in 7th grade too but what the **** r u studying????

Answer 2

Well as written no chance because there are only 3 neon brushes between 100 people :-)

But, if you say what is the chance of one person picking one neon toothbrush an one grape gum from that selection.

Toothbrush 3 chances in 5 = 60%

Gum 3 chances in 4 = 75%

Combined chance of the combination = 45%

Then multiply by 100 people would be 45 people.

Answer 3

take the number of the toothbrush and divide it by nine. THen move the decimal place over two spots to the left.
