Hannah's teacher brought in a bucket containing 72 blocks. The blocks are red, yellow or blue. Hannah wants to figure out the number of blue blocks without emptying the bucket.
Hannah chooses a block from the bucket records its color and then replaces it. Of her 14 draws she records blue 5 times. Based on Hannah's experiment how many blocks are blue?

prob(blue) = 5/14
so (5/14)(72)
= 25.7
or appr 26 could be blue
