Question 385380
a box of colored thumb tacks contains 80 tacks, with an equal assortment of red, green, blue, and yellow tacks. if you close your eyes and select a single thumb tack , what is the probability that it will not be red?
------------------
There are 20 tacks of each color.
P(not red) = 60/80 = 3/4
