<PRE><B>Question 1165451</B>
a. 23% are orange so 0.77 probability not orange.

b. brown or orange is 0.35 probability 

c. both green would be (15/100)*14/99=0.0212

d. none is red when 6 chosen
denominator is 100C6, number of ways to choose 6 out of a 100.
88 out of 100 are not red
so 88C6 are ways to pick one of those.

it is 88C6/100C6=0.4546

way 2
88/100 probability first is not red*87/99*86/98*85/97*84/96*83/95=0.4546

e. at least one of them is red is the complement, since it is a dichotomy, and that probability is 0.5454.
