Hi,
An unfair coin comes up heads 52.7% of the time. The coin is flipped a total of 19 times.
 A) what is the probability you get exactly 12 heads? 
(19C12)(.527)^12(.473)7= .1335 (not sure if correct)  {{{.1225}}}
B) What is the probability that you get exactly 11 tails?
 (19C11)(.473)^11(.527)^8= .1338 (again not sure)  {{{.1192}}}
C) What is the probability that you get at most 16 tails?
   P = 1 -P(17T) - P(18T) - P(19T) =  .9998
