Answer:
See explanation
Step-by-step explanation:
Given
[tex]n=5[/tex] --- disks
[tex]p = \frac{1}{3}[/tex] --- success probability
Required
The question is incomplete, as the required probability is not stated.
However, the question follows binomial distribution and the probability is calculated using:
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n-x}[/tex]
Assume the question requires that we calculate the probability that he's able to drop 2 disks, the probability will be:
[tex]P(x = 2) = ^5C_2 * (\frac{1}{3})^2 * (1 - \frac{1}{3})^{5-2}[/tex]
[tex]P(x = 2) = ^5C_2 * (\frac{1}{3})^2 * (\frac{2}{3})^{3}[/tex]
[tex]P(x = 2) = 10 * \frac{1}{9}* \frac{8}{27}[/tex]
[tex]P(x = 2) = \frac{80}{243}[/tex]
