Answer:
Step-by-step explanation:
The probability mass function P(X = x) is the probability that X happens x times.
When n trials happen, for each , the probability mass function is given by:
In which p is the probability that the event happens.
is the permutation of n elements with x repetitions(when there are multiple events happening(like one passes and two not passing)). It can be calculated by the following formula:
The sum of all P(X=x) must be 1.
In this problem
We have 3 trials, so
The probability that a wafer pass a test is 0.7, so
Determine the probability mass function of the number of wafers from a lot that pass the test.

Step-by-step explanation:
The radical can be simplified by breaking it down into factors and removing the perfect squares from inside the radical.
25 is a perfect square and is 5 outside the radical.
is a perfect square and is x outside the radical.
is a perfect square and is
outside the radical.
