Step-by-step explanation:
We have that, a die is rolled once.
As, the total outcomes can be 1, 2, 3, 4, 5, 6.
So, the probability to obtain 2 is and the probability to obtain 6 is
.
Thus, the probability of rolling 2 or 6 after rolling a die once will be i.e.
.
Hence, the probability of rolling a 2 or 6 is .
Answer:
Arc length is , or, 14.7
