The answer is X>-7 for your question
Total voters=v=80
total no. of democrats=d=65
total no. of republicans=r=15
probability of democrats=p1=65/80=0.8125
probability of republicans=p2=15/80=0.1875
probability of a democrat or a republican=p1+p2=0.8125+0.1875=1 <span />
If the sample is random, it is not valid.

==================================================
Explanation:
If we could tell the repeated letters apart, then there would be
11*10*9*8*7*6*5*4*3*2*1 = 39,916,800
different ways to scramble up the letters.
However, we have 2 copies of b and 2 copies of i
So we have to divide by 2*2 = 4 to correct this overcounting
(39,916,800)/4 = 9,979,200
