**Reiny**, Tuesday, April 16, 2013 at 11:52pmin #1, are you picking just one? I will assume that

Prob(1 red) = 4/35 = appr .114 which is 11.4%

you had the right answer

#2

There are 4 numbers > 3

so prob (>3) =**4/6**= 2/3

(they should have reduced the fractions)

#3

prob of correct guess = 1/5

prob of wrong guess = 4/5

odds in favour of correct guess = (1/5) : (4/5)

= 1 : 4
