Answer:
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 (<em>k</em>) before the first success.
The probability function of Geometric distribution is:
, <em>p</em> = Probability of success and <em>k</em> = 0, 1, 2, 3...
The probability of success is, <em>p</em> = 0.5 and the number of failures is, <em>k</em> = 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.
There ya go! Hope this helped
The equation given in the question is
5x^2 - 5x - 100 = 5x^2 - 25x + 20x - 100
= 5x(x - 5) + 20(x - 5)
= (5x + 20)(x - 5)
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
