Short answer

True statement

Step-by-step solution

Step 1. Given Information. 

True or False In a probability model, the sum of all probabilities is 1.

Step 2. True or False. 

In a probability model, the sum of all probabilities is 1 because if you have one experiment with different outcomes, then the probability of those outcomes to occur is just between 0 to 1 and if you will add them together, their sum will be equal to 1.

Step 3. Conclusion.

The given statement is true.
