in which scenario do you use geometric distribution to solve?
find the number of times a tossed coin lands on tails in 10 trials.
determine the probability of tossed coin and landing on tails.
find the probability of not getting tails until the 6th toss of the coin.
determine the number trials to do to have a tossed coin land on tails 8 times.

Explanation:

The geometric distribution is used to find the probability that the first success occurs on a certain trial. In the case of coin - tossing, success can be getting tails. Finding the probability of not getting tails until the 6th toss is about the first success (getting tails) occurring on the 6th trial. The first option is a binomial situation (number of successes in a fixed number of trials), the second option is a simple probability calculation, and the fourth option is related to negative - binomial distribution (number of trials to achieve a fixed number of successes).

Answer:

Find the probability of not getting tails until the 6th toss of the coin.
