There is a 1 in 4 chance that on any given sexual encounter, Joe will contract an STD. If Joe has sex 4 times, what are the chances of him having an STD?
The formula for calculating the probability of an event occurring at least once over n trials is 1 - (1-p)^n, where p is the probability of the event occurring in a single trial.
The probability of an event occurring at least once over n trials takes into account all possible outcomes where the event occurs once, twice, three times, and so on, up to n times. The probability of the event occurring exactly once only considers the outcome where the event occurs once and does not take into account any other possible outcomes.
The number of trials has a direct impact on the probability of an event occurring at least once. As the number of trials increases, the probability of the event occurring at least once also increases. This is because with more trials, there are more opportunities for the event to occur.
Yes, the probability of an event occurring at least once is affected by the probability of the event occurring in a single trial. The higher the probability of the event occurring in a single trial, the higher the probability of the event occurring at least once over n trials.
No, the probability of an event occurring at least once over n trials can never be greater than 1. This is because the maximum probability of an event occurring in a single trial is 1, and as the number of trials increases, the probability of the event occurring at least once approaches 1 but never exceeds it.
