Final answer:
The question asks to calculate the probability of no more than 73 out of 117 software users not calling technical support, with each user having a 65% chance of cannot be determined. It is a binomial probability problem, but the answer cannot be determined without further calculation using the probabilities given or a calculator.
The correct answer is 4).
Step-by-step explanation:
The question revolves around finding the probability that no more than 73 out of 117 software users will not call technical support, given the probability that a given software user will not call technical support is 65%. This falls into the category of a binomial probability problem, where the number of successes in a sequence of n independent experiments is counted. In this case, labeling a user who does not call as a 'success'.
To solve this, one must apply the binomial probability formula or use a TI-83/84 calculator to compute the cumulative probability of getting 0 through 73 successes out of 117 trials with a success probability of 0.65. The exact answer to the student's question depends on the calculation of this cumulative probability, which isn't provided directly in the options, therefore the answer cannot be determined from the given choices without further calculation.
