Probability of Rolling a Biased Die

Hard Data Analysis And Probability Probability

Consider a six-sided die that is biased, such that:

- The probability of rolling a 1 is 0.1

- The probability of rolling a 2 is 0.2

- The probability of rolling a 3 is 0.2

- The probability of rolling a 4 is 0.2

- The probability of rolling a 5 is 0.2

- The probability of rolling a 6 is 0.1

What is the probability that when rolling the die three times, the outcome will consist of at least one instance of rolling a 1?
