5/12 hour = 1 piano solo's
15/12 hour = 3 piano solo's
Simplifying 15/12 hours we get:
<u>1.25 hours also known as 1 hour 15 minutes</u>
I belive the answer is 1.
This is because out of 22 ribbon there are 10 which are bue so the probability of blue ribbons is 10/22 and probability of red ribbon is 12/22. So your question was the probability of choosing a red ribbon then a blu ribbon. Because of the word "then" , this means it is simply asking you to add their probablity so after adding 10/22 with 12/22 your answer will come to 22/22 which is equal to 1.
