A spinner is divided into 12 equal sections where 5 of the sections are red, 3 are blue, 2 are orange, and 2 are green. What are the frequencies of each color if you spend the spinner 60 times?

I know I asked this question before but I wanted to check if my answer was correct.
Red = 5/60 = 1/12
Blue = 3/60 = 1/20
Orange = 2/60 = 1/30
Green = 2/60 = 1/30
those are the respective frequencies of each color
correct?

I think I answered this for you partially several days ago, but since you don't give yourself a "name", I cannot find the posting.

I recall showing you how to get the probabilities of getting the different colours, and then telling you to multiply each of those by 60.

I don't know what you did.

prob(red) = 5/12 , frequency = (5/12)(60) = 25
prob(blue) = 3/12, frequencey = (3/12)(60) = 15
prob(orange) = 2/12, frequ. = (2/12)(60) = 10
prob(green) = 2/12, frequ. = (2/12)(60) = 10

notice my probabilites add up to 1, as needed
and my frequencies add up to 60 , as needed

I told you what had to be done, you did not follow my instructions.
