At WSU hospital, 64% of patients have water on the knee, 45% have butterflies in the stomach, and 20% have both conditions. What is the probability that a random patient has neither condition? What is the probability that a random patient has exactly one of the two conditions?
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.
At WSU hospital, 64% of patients have water on the knee, 45% have butterflies in the stomach, and 20% have both conditions. What is the
conditions?
Given:
suppose
A = patient is having water on the knee
B = patients are having butterflies in the stomach
Calculation:
the probability that an arbitrary patient has neither condition =
Required Probability is 0.11
