Solution

(26)A \"law of large numbers\" is one of several theorems expressing the idea that as the number of trials of a random process increases, the percentage difference between the expected and actual values goes to zero.

--------------------------------------------------------------------------------------------------------------

(27)(a) The probability is

(325+52)/864 = 0.4363426

***********************************************************************************

(b) P(prison sentence|not guilty)

=P(P(prison sentence and not guilty)/P(not guilty)

=52/(52+12)

=0.8125

***********************************************************************************

(c) P(entered a plea of not guilty or not sentenced to prison)

=P(entered a plea of not guilty) + P(not sentenced to prison) - P(both)

=52/864 + (475+12)/864 - 0

=0.6238426

***********************************************************************************

(d) number of NOT Guilty Plea=52+12 =64

So the probability that both defendants entered a \"not guilty\" plea is

64*63/(864*863)

=0.005407493

***********************************************************************************

(e) 475/ 864 = 0.5497685

--------------------------------------------------------------------------------------------------------------

(28)(a) 20C5 = (20*19*18*17*16)/(1*2*3*4*5) = 15504

***********************************************************************************

(b)20C3 = (20*19*18)/(1*2*3) = 1140
