The sample space is (6,1),(6,2),(6,3),(6,4),(6,5)(2,6),(1,6),(3,6)(4,6),(5,6),(6,6). The Favorable outcome is (6,1),(6,2),(2,6) and(1,6). The probability is 4/11=4/11
Laura read 3 times as many books as Kami, but possibly less than Cecile.
Gigi read 30 books. 30 books is the same as all 3 girls combined.
To find out how many books each girl read, you need to find 3 unequal numbers that add up to 30. These numbers are substituted, only because they can be anything at all, and I want to prevent confusions.
