How to Calculate Binomial Probabilities on a TI-84 Calculator

WebEvery function with these four properties is a CDF, i.e., for every such function, a random variable can be defined such that the function is the cumulative distribution function of that random variable. WebFor example, consider the height of an adult male in the United States. We can use the cumulative distribution function to find the probability that a person is less than or equal to 6 feet tall. For CDF’s, we need to specify the type of distribution (e.g., normal, Weibull, binomial, etc.) and its parameters—just like we do for PDFs.

WebThe cumulative distribution function (" c.d.f.") of a continuous random variable X is defined as: F ( x) = ∫ − ∞ x f ( t) d t. for − ∞ < x < ∞. You might recall, for discrete random variables, that F ( x) is, in general, a non-decreasing step function. WebThe Cdf class provides these two methods: PercentileRank (x) Given a value x, computes its percentile rank, . Percentile (p) Given a percentile rank rank, computes the corresponding value, x. Equivalent to Value (p/100). Percentile can be used to compute percentile-based summary statistics.

This makes sense since F X ( t) is a probability. If X is a discrete random variable whose minimum value is a, then F X ( a) = P ( X ≤ a) = P ( X = a) = f X ( a). If c is less than a, then F X ( c) = 0. If the maximum value of X is b, then F X ( b) = 1.
