You can put this solution on YOUR website! all male jury of 12 peopke is chosen for a trial. The defense lawyer claims the jury must have been chosen in a biased manner because 50% of the city's adult residents are women and yet the jury contains no women. Assess the claim by answering the following:
If the jury were randomly chosen from the city's adult population , what is the probability that the jury would have
a) no females,
P(x = 0 of 12) = (1/2)^12 = 0.0002441
-------------------
b) at least one female?
P(at least one) = 1 - P(no female)
= 1 - 0.0002441
= 0.999756...
