Normalcdf ti84
On a TI-84 calculator there are two functions you can use to find probabilities related to the binomial distribution: binompdf (n, p, x): Finds the probability that exactly x successes occur during n trials where the probability of success on a given trial is equal to p. binomcdf (n, p, x): Finds the probability that x successes or fewer occur ...Token Size. normalpdf ( is the normal (Gaussian) probability density function. Since the normal distribution is continuous, the value of normalpdf ( doesn't represent an actual probability - in fact, one of the only uses for this command is to draw a graph of the normal curve. You could also use it for various calculus purposes, such as finding ...TI-84 Plus CE - Incorrect Value of Normalcdf . My Teacher is saying that the answer to: normal(-1e99, -4.47,0,1) = 0.0000 (because it is a microscopic answer) My TI-84 CE is saying that normal(-1e99, -4.47,0,1) = 3.91445422e-6 I have done a factory reset on the calculator and I am still getting the same answer, any help?
