An eight sided dice is rolled 3 times. What is the probability of getting three 7's?

Answer 1

#1/8^3=1/512#.

Each throw is unconditional and the probability of showing 7 in a throw = (the number of favorable cases)/(total number of cases = 1/8. For appearance of 7 in three consecutive throws, the probability is the combined probability = product of the probabilities for the separate throws = #1/8^3#..

To find the probability of rolling three 7's with an eight-sided dice rolled three times, you need to multiply the probability of rolling a 7 on each roll. The probability of rolling a 7 on a single roll of an eight-sided dice is 1/8. Therefore, the probability of rolling three 7's in a row is (1/8) * (1/8) * (1/8) = 1/512.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
