      We are ready to graph the discrete probability distribution. Press GRAPH. Press TRACE and notice that a blinking cursor appears over the first bar. The probabilities P(x) are given by n. Use the right and left arrow keys to move from bar to bar. To leave the discrete probability distribution, press 2nd QUIT.

      Let X = the number of “successes” in a binomial experiment with n trials, where p is the probability of success. P(X = r) = n C r (p)r (1 – p)n – r . On the calculator: binompdf (n, p, r) = P(X = r) binomcdf (n, p, r) = P(X ≤ r) 1. About 85% of students at a local high school favor school-sponsored extracurricular activities. If 20 ...

      P(X< 100). To use the normal approximation to calculate this probability, we should first acknowledge that the normal distribution is continuous and apply the continuity correction. This means that the probability for a single discrete value, such as 100, is extended to the probability …

      4. binompdf (n, p, X): Finds the probability of x number of successes in a binomial setting. 5. binomcdf (n, p, X): Finds the probability of x or fewer successes in a binomial setting. Ex: The probability of randomly guessing correctly at a multiple choice question is .2.

      Binomcdf(n, p, r) Select binomcdf from the calculator list. In the open parenthesis, we enter n, p, r. n = number of trials/observations. p = probability of success. r = desired number of successes. Important Note: Binomcdf only finds the probability that the number of successes is less than or equal to the desired value. It always finds P(x < r).

      In general, the probability that x gets a value c, P(x=c), is defined as . the sum of all corresponding outcomes in S (i.e., the sample space) that are assigned to the value . x. Ex. x = # of heads in tossing 2 fair coins. 3. There are 3 ways to display a probability distribution for a discrete r.v.:

      If X has a binomial distribution with n observations and probability p of success on each observation, the possible values of X are 0, 1,2,3,…,n. If k is any one of these values, then. The Probability Distribution Function (pdf) assigns a probability to each value of X. On your calculator, you can use binompdf (n, p, …
