Thanks! Well I did 6! x 3! as the white roses being together as you would consider the 3 roses as a group and therefore there would be 6! ways of arranging them with the 5 roses and 3! ways of themselves being arranged in their own group. My wording is not probably the best but that's how I usually tackle these sorts of questions and I'm not sure why this method doesn't get me to the answer like it usually does. Do u know y that is the case?
I follow you! That covers cases with
all three white roses together, but if you think carefully, it actually doesn't cover two at a time. So, you aren't subtracting enough cases, which is why your answer is higher than it should be
I love the method you use, and often it works really well, just not in this case, you need to be
very careful with probability!
