Question 374935: A controversy arose in 1992 over the Teen Talk
Barbie doll, each of which was programmed with four sayings
randomly picked from a set of 270 sayings. The controversy
was over the saying, “Math class is tough,” which
some felt gave a negative message toward girls doing well
in math. In an interview with Science, a spokeswoman for
Mattel, the makers of Barbie, said that “There’s a less than
1% chance you’re going to get a doll that says math class
is tough.Ӡ Is this figure correct? If not, give the correct
figure.
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! Assuming the 4 sayings are different (without replacement), the chances are
1/270 + 1/269 + 1/268 + 1/267
=~ 0.0149 = 1.49%
----------------
If it's possible to get the same saying more than once, it's
4/270 =~ 0.148 = 1.48%
--------
Either way, it's more than 1%
