**Reiny**, Monday, January 28, 2013 at 1:31pmUnfortunately, this is not as simple as "cassi's" solution

This is a binomial distribution problem

We have to find the sum of the following cases

prob(none has one) + prob(1 of the 10 has one) + ... + prob (5 of 10 have one)

= C(10,0) (.6)^0 (.4)^10 --> .0001049

+ C(10,1) (.6)^1 (.4)^9 --> .001573

+ C(10,2) (.6)^2 (.4)^8 --> .0106168

+ C(10,3) (.6)^3 (.4)^7 --> .042467

+ C(10,4) (.6)^4 (.4)^6 --> .1114767

+ C(10,5) (.6)^5 (.4)^5 --> .200658

= appr .3244

(might be a good idea to check my calculations)
