Many fire stations handle emergency calls for medical assistance as well as calls requesting firefighting equipment. A particular station says that the probability that an incoming call is for medical assistance is 0.74. This can be expressed as P(call is for medical assistance) = 0.74 (c) Still assuming independence, calculate the probability that exactly one of the next two calls will be for medical assistance. (Hint: There are two different possibilities. The one call for medical assistance might be the first call, or it might be the second call.) (d) Do you think that it is reasonable to assume that the requests made in successive calls are independent? Explain. Yes, calls for medical assistance are more likely to come all throughout the day, thus they are independent. Yes, calls for medical assistance are more likely to come all throughout the day, thus they are not independent. No, calls for medical assistance are more likely to come at certain times of day, thus they are independent. No, calls for medical assistance are more likely to come at certain times of day, thus they are not independent.
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.
