Answer:
Step-by-step explanation:
The probability of rolling a 1 is 0.85; then the probability of rolling not 1 is
1 - 0.85 = 0.15
Each box that states rolling a 1 gets 0.85. Each box that states not rolling 1 gets 0.15.

Here a "success" is "obtaining a 7 or a 5." Assuming that the 10-sided die is marked {1, 2, 3, ... , 9, 10}, there are 2 ways in which to get a "success" out of 10 possible outcomes. Thus, P(5 or 7) is 2/10, or 1/5, or 02.
