- Let X denote the number of siblingsof a randomly selected student. Explain the difference between {X=3} and P(X=3). Choose the correct answer below. A. {X=3} is the relative frequency that a student has three siblings; P(X=3) is the frequency that a student has three siblings. B. {X=3} is the frequency that a student has three siblings; P(X=3) is the relative frequency that a student has three siblings. C. {X=3} is the probability of the event that the student has three siblings; P(X=3) is the event that the student has three siblings. D. {X=3} is the event that the student has three siblings; P(X=3) is the probability of the event that the student has three siblings.Find the interquartile range.
