Hallie is trying to win the grand prize on a game show. Should she try her luck by spinning a wheel with 6 equal sections labeled from 1 to 6 and hope she gets a 5, or should she roll two number cubes and hope she gets the same number on both cubes. Show your work?
C. There is a greater chance in picking to purple marbles because there are less of the white and more purple.
Hallie should spin the wheel because u have a greater chance of landing on a 5 then rolling two number cubes and hoping both number cubes come to equal 5.
two white marbles:
probability first is white is \frac{2}{9}
probability second is white given that the first is white is \frac{1}{8}
again probability both happen is
\frac{2}{9}\times \frac{1}{8}
