To find the probability \( P(\text{less than } 3) \) for a weighted number cube, we need to identify which outcomes are "less than 3." For a standard six-sided die, the outcomes are 1, 2, 3, 4, 5, and 6.
The outcomes that are less than 3 are 1 and 2.
Next, you would typically need the probabilities of rolling a 1 and a 2, which should be provided in the probability model you mentioned. If you have that data available, you would compute \( P(\text{less than } 3) \) as follows:
\[ P(\text{less than } 3) = P(1) + P(2) \]
Once you have the probabilities \( P(1) \) and \( P(2) \) from the model, simply add them together to find \( P(\text{less than } 3) \).
If you provide the specific probabilities for each outcome, I can help you with the calculation.
