90/185 are brown

95/185 are pink

Those same values are the probabilities of picking one.

Don't be put off by the big numbers. If there had been 1 brown and 2 pink, would you have had trouble?

**zero probability**, Wednesday, April 17, 2013 at 3:12pma) 95+90=185

therefore: Ppink=95/185

=19/37

b) Pbrown=90/185

=18/37
