Hi,
Note: The probability of x successes in n trials is: 
P = nCx* {{{p^x*q^(n-x)}}} where p and q are the probabilities of success and failure respectively. 
In this case p(w/o insurance)= 1/6 & q = 5/6 and n = 8
8 transplants are selected at random
P(none from w/o ins)= {{{8C0(1/6)^0(5/6)^8}}}
P(8 from w/o ins) = {{{8C8(1/6)^8(5/6)^0}}}
