Explanation Let x be the number of patients who will have a positive response to treatment. Here, n = 20 and p = 0.16. The probability that at least 3 of the patients will have a positive response to treatment is calculated as follows: P ( x ≥ 3 ) = 1 − P ( x ≤ 2 ) = 1 − [ C 20 0 ( 0.16 ) 0 ( 1 − 0.16 ) ( 20 − 0 ) + C 20 1 ( 0

Compound Probability

Compound probability can be defined as the probability of the two events which are independent. It can be defined as the multiplication of the probability of two events that are not dependent.

Tree diagram

Probability theory is a branch of mathematics that deals with the subject of probability. Although there are many different concepts of probability, probability theory expresses the definition mathematically through a series of axioms. Usually, these axi…

Conditional Probability

By definition, the term probability is expressed as a part of mathematics where the chance of an event that may either occur or not is evaluated and expressed in numerical terms. The range of the value within which probability can be expressed is between…
