Te probability is 0.5 that an artist makes a craf item with satisfactory quality. assume the production of each craf item by this artist is independent. what is the probability that at most 3 attempts are required to produce a craf item with satisfactory quality?

The probability that at most 3 attempts are required to produce a craft item with satisfactory quality is 0.9375

Step-by-step explanation:

Let E be a random variable denoting the event that an artist makes a craft item with satisfactory level.

Then the random variable E follows a Geometric distribution.

A Geometric distribution is defined as the number of failures (k) before the first success.

The probability function of Geometric distribution is:

, p = Probability of success and k = 0, 1, 2, 3...

The probability of success is, p = 0.5 and the number of failures is, k = 3.

Compute the probability of at most 3 attempts before the first success is:

Therefore, the probability that at most 3 attempts are required to produce a craft item with satisfactory quality is 0.9375.
