c) In a sample of 100 newly manufactured automobile tires, 7 are found to have minor flaws in the tread. If four newly manufactured tires are selected at random and installed on a car. Suggest a statistical method/formula to use if you want to estimate the probability that none of the four tires have a flaw? i. ii. Define the random variable in the problem 3c) and hence, the distribution of such random variable?

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Two methods have been developed to determine the nickel content of steel. In
a sample of five replications of the first method on a certain kind of steel, the
average measurement (in percent) was = 3.16 and the standard deviation
was s, = 0.042. The average of seven replications of the second method was
ỹ = 3.24 and the standard deviation was s = 0.048.
a) Determine if there is a difference in the mean measurements between
the two method and explain the most likely assumption that could be
made before solving this problem?
b) What informed your choice of solution method?
