Assume that 12 jurors are randomly selected from a population in which 79% 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	0.0007
5	0.0044
6	0.0193
7	0.0621
8	0.146
9	0.2442
10	0.2756
11	0.1885
12	0.0591

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.
$\displaystyle {P}{\left({x}\le{7}\right)}=$

Assume that any probability less than 5% is convincing enough evidence to suspect discrimination. Does 7 Mexican-Americans among 12 jurors suggest that the selection process discriminates against Mexican-Americans?
