Question:

A jury has 12 jurors. A vote of at least 10 of 12 for "guilty" is necessary for a defendant to be convicted of a crime. Assume that each juror acts independently of the others and that the probability that any one juror makes the correct decision regarding a defendant is .70. If the defendant is guilty, what is the probability that the jury makes the correct decision?
