Assume that 12 jurors are randomly selected from a population in which 78% of the people are Mexican-Americans. Refer to the probability distribution table below and find the indicated probabilities.

$\displaystyle {x}$	$\displaystyle {P}{\left({x}\right)}$
0	0+
1	0+
2	0+
3	0.0001
4	0.001
5	0.0057
6	0.0236
7	0.0717
8	0.1589
9	0.2503
10	0.2663
11	0.1717
12	0.0507

Find the probability of exactly 7 Mexican-Americans among 12 jurors.
$\displaystyle {P}{\left({x}={7}\right)}=$

Find the probability of 7 or fewer Mexican-Americans among 12 jurors.
$\displaystyle {P}{\left({x}\le{7}\right)}=$

Does 7 Mexican-Americans among 12 jurors suggest that the selection process discriminates against Mexican-Americans?
