Question

Dan tosses a fair pyramid die that has four sides 5 times. What is the probability he rolls at least 1 two? If necessary, round to 4 decimal places.

Answer 1

The probability of rolling at least 1 two when tossing a fair pyramid die 5 times is approximately 0.7627.

Step-by-step explanation:

To find the probability of rolling at least 1 two when tossing a fair pyramid die with four sides 5 times, we can calculate the complement of the event 'not rolling any twos'. The probability of not rolling a two on a single toss is 3/4, since there are 3 other sides. The probability of not rolling any twos in 5 tosses is (3/4)^5. So, the probability of rolling at least 1 two is 1 - (3/4)^5, which is approximately 0.7627.
