12 total roses.

Probability of selecting a pink rose would be 3/12 or 1/4.
p(pink)=3/12=1/4

The complement of that would be 1-1/4=3/4.

P(NOT pink)=1-1/4=3/4

So theres a 3/4 chance that she WON'T randomly select a pink rose.

Please help this is my last question for this page and I'm stuck on it
Lena [83]

put a 1 under the 13, so it is 13/1, and 5 5/6, turn it into an improper fraction by multiplying 5x6=30. then 30+5, which is 35. so just keep the denominator, which would be 35/6. so you would have 13/1 - 35/6. you need the same denominator, so see what both 1 and 6 would fit into. which is 6. so 13x6 which is 78, so 78/6 - 35/6, so 78-35 is 43. so 43/6, then simplify, which is 7 1/6
