Mickie has a spinner with 10 equal sections. What is the probability of landing on either a green or a blue section?
4 red, 4 green, 2 blue
There are a total of 10 sections on the spinner.
The probability of landing on a green section is 4/10 = 0.4
The probability of landing on a blue section is 2/10 = 0.2
Therefore, the probability of landing on either a green or a blue section is 0.4 + 0.2 = 0.6.
as a fraction please
The probability of landing on a green section is 4/10 and the probability of landing on a blue section is 2/10.
Therefore, the probability of landing on either a green or a blue section is:
4/10 (green) + 2/10 (blue) = 6/10 = 3/5
