Question 368830
Let X = # left-handed people in a sample of 2 people.  Then the possible values of X are 0,1,2.
The probability distribution (which is actually a hypergeometric distribution) is as follows:
{{{p(0) = (C(3,0)*C(9,2))/C(12,2) = 6/11}}},
{{{p(1) = (C(3,1)*C(9,1))/C(12,2) = 9/22}}},
{{{p(2) = (C(3,2)*C(9,0))/C(12,2) = 1/22}}}.
