To complete the table, we need to calculate the probabilities for the other three scenarios: purchasing 10 or more coins, spending 3 or fewer hours per week, and both purchasing 10 or more coins and spending 3 or fewer hours per week.
Let's use the given information to calculate these probabilities:
1. Probability of purchasing 10 or more coins:
The probability of purchasing fewer than 10 coins is 0.6. Therefore, the probability of purchasing 10 or more coins is 1 - 0.6 = 0.4.
2. Probability of spending 3 or fewer hours per week:
The probability of spending greater than 3 hours per week is 0.25. Therefore, the probability of spending 3 or fewer hours per week is 1 - 0.25 = 0.75.
3. Probability of both purchasing 10 or more coins and spending 3 or fewer hours per week:
To calculate this probability, we need to multiply the individual probabilities. The probability of purchasing 10 or more coins is 0.4, and the probability of spending 3 or fewer hours per week is 0.75. Therefore, the probability of both scenarios happening is 0.4 × 0.75 = 0.3.
Now, we can complete the table:
| Scenario | Probability |
|------------------------------------------|-------------|
| Purchased fewer than 10 coins | 0.6 |
| Purchased 10 or more coins | 0.4 |
| Spent greater than 3 hours per week | 0.25 |
| Spent 3 or fewer hours per week | 0.75 |
| Purchased 10 or more coins and spent 3 or fewer hours per week | 0.3 |
These values complete the table based on the given probabilities.
