Food-grade lubricants must perform the same technical functions as any other lubricant: provide protection against wear, friction, corrosion and oxidation, dissipate heat and transfer power, be compatible with rubber and other sealing materials, as well as provide a sealing effect in some cases.
Using the binomial distribution, it is found that there is a:
- 0.0036 = 0.36% probability that both are allergic to pollen.
- 0.1164 = 11.64% probability that at least one is allergic to pollen.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
Researching the problem on the internet, it is found that:
- 6% of the population is allergic to pollen, hence p = 0.06.
- Two people are chosen at random, hence n = 2.
The probability that both are allergic is P(X = 2), hence:
P(X = 2) = 0.06^2 = 0.0036.
0.0036 = 0.36% probability that both are allergic to pollen.
The probability of at least one is:
P(X >= 1) = 1 - P(X = 0) = 1 - 0.94^2 = 1 - 0.8836 = 0.1164.
0.1164 = 11.64% probability that at least one is allergic to pollen.

The way that the author portrays Scotty in the given excerpt is that; A: His confidence is transformed by the crowd’s response
<h3>What does the authors excerpt portray?</h3>
The given excerpt is taken from a fiction book titled "A Visit from the Goon Squad" written in 2011 by American author Jennifer Egan.
At the beginning of the excerpt, we have a clear clue that would lead us to the fact that his confidence is transformed by the crowd's response which is that "... a swell of approval palpable as rain lifted from the center of the crowd and rolled out toward its edges...".
The meaning of that quoted statement at the beginning of the excerpt is that the crew was encouraging him due to the fact that they liked what they were watching and feeling. Thus, the passage describes how the crew reacted and how it gave strength to him to go on the stage and perform on it.
