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.
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.
