Hey, this question is confusing me a little bit, I think the answer is 1- ($\frac{59}{60}$)^10 because it is 1- P(dont get the disease) and the probability that u dont get the disease from one person is (59/60) so u do 1- that and to the 10th power because there are 10 people. Is this correct? |

I think thats right! In my notes from discussion I had written down 1-(1-p)^10 where p= $\frac{1}{10}$ x $\frac{1}{6}$ but i was confused why it was written in there twice but what you said makes sense and goes right along with what we learned in discussion. |

The 1- is in there twice because the first time you want to find the compliment, the second time is to negate the probability (explanation on the discussion labelled B6 :) |
