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.
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.
To answer the given questions, we need to utilize the provided information about the spinner outcomes and probabilities.
1. The sum of the probability model:
To find the sum of the probability model, we add up the probabilities of all possible outcomes:
1/5 (white) + 2/5 (green) + 2/5 (red) = 5/5 = 1
Therefore, the sum of the probability model is equal to 1.
2. The probability of spinning the spinner and landing on red:
According to the given information, the probability of landing on red is 2/5. So, the answer is 2/5.
3. The probability of not landing on red:
To find the probability of not landing on red, we need to subtract the probability of landing on red from 1 (since the sum of all probabilities is 1). Using the probability of spinning and landing on red (2/5), we have:
1 - 2/5 = 3/5
Therefore, the probability of not landing on red is 3/5.
The sum of the probability model is found by adding up the probabilities of all the outcomes:
1/5 + 2/5 + 2/5 = 5/5 = 1
So, the sum of the probability model is 1.
The probability of spinning the spinner and landing on red is given as 2/5.
The probability of not landing on red is obtained by subtracting the probability of landing on red from 1.
So, 1 - 2/5 = 3/5.
Therefore, the probability of not landing on red is 3/5.
