- Probability PLEASE HELP -
**Reiny**, Thursday, November 24, 2011 at 8:23amnumber of ways that the 3 reds and the 2 whites

can be arranged = 5!/(3!2!) = 10

Now place a white at the end, then the number of ways to arrange the remaining 4 is 4!/(2!2!) = 6

so prob that the last one will be white = 6/10 = 3/5
