Allison spins a spinner that has 3 3 red spaces, 4 4 blue spaces, and 2 2 green spaces. If all the spaces have an equal chance of being selected, what is the probability that Allison will spin a green or a blue? Enter your answer as a fraction, in lowest terms, using the / symbol, like this: 42/53

Respuesta :

first of all, how many spaces does the spinner have? if you add up the 3 red, 4 blue, and 2 green spaces (I don't know what the double numbers mean) you get 9, so we will work off of that, since there are 3 different color spaces we'll say the chance of spinning a color is 3/9. so the chance of spinning a blue or green is 6/9. make it to lowest terms and you get 2/3
