I would need help with this question:
Suppose you are a lawyer representing a Hispanic individual in a criminal trial. Twelve jurors are randomly selected by the state from a population that you know to be 50% Hispanic.
a). How many jurors would you expect to be Hispanic? 6
b). The select process produces a jury with 1 Hispanic individuals What proportion of the jury is Hispanic? (Enter your answer as a decimal, rounded to four decimal places)  0.0833
c). Use the binomial distribution and find the probability that 1 or fewer jurors would be Hispanic. 0.0032

Is this the correct graph? Create a graph of the distribution with the area corresponding to the previous answer shaded in. Use Excel, Binomial Distribution Calculator (in resources menu), TI-84 (take a pic), hand drawn, other software, websites.
