obtained. When a 1 is obtained, the experiment is over, but the 1 is included in the sequence. Thus every outcome is a sequence of integers ending

in 1. Let X be the sum of the sequence of numbers obtained in the experiment. So the smallest possible value of X is 1, corresponding to the outcome

in which a 1 is obtained on the first toss.

Compute P(X=5).

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

For five tosses:

(5/6)^4 * 1/6 = ?
