Answer 1

Objection to #6, 9, and 10

#6, you have
6 green
4 red
5 yellow
3 purple
Prob(purple) = 3/18 = 1/6

#9
(7/24)(6/23) = 42/552
= 7/92 , your 42/552 is correct , but should be reduced to lowest terms

#10
6 letter, of which you have 2 r's,
The problem is: Do you consider y a vowel or consonant

if y is a vowel, your answer is
(2/6)(2/6) = 1/9
if y is a consonant, your answer is (2/6)(1/6) = 1/18

don't know how you got 25 in the denominator.
