Question

use the spinner to answer the questions,
outcomes: white, green, red
probability: 1/5, 2/5, 2/5
The sum of the probability model is
The probability of spinning the spinner and landing on red is
The probability of not landing on red is choose
landing on red.

Answer 1

The sum of the probability model is 1 since the total probability of all outcomes must equal 1.

The probability of spinning the spinner and landing on red is 2/5 or 0.4.

The probability of not landing on red is 3/5 or 0.6, which is 1 minus the probability of landing on red.
