Answer 2

There are only 3 different colors on the spinner - red, blue, and green. We are told that 10% of these sections are blue and 20% are red. So, starting with a probability of 100/100, we simply need to subtract our known values from the total, and the remaining value will be the probability of landing on the rest of the sections (the green ones):

100/100 - 10/100 = 90/100
90/100 - 20/100 =70/100.

The probability of landing on a green section is 70/100, or 70%.
