In general, you can skip parentheses, but be very careful: e^3x is `e^3x`, and e^(3x) is `e^(3x)`. ), etc. This finds the probability of a single value. Choose 95% for the area, so that the top tail has a probability of 5%. OK. Well, I do understand Pascal's triangle, etc., etc., and I know how to calculate the binomial coefficient without the calculator (5C2 is basically 5!/(2!*3! You can use this tool to solve either for the exact probability of observing exactly x events in n trials, or the cumulative probability of observing X ≤ x, or the cumulative probabilities of observing X < x or X ≥ x or X > x.Simply enter the probability of observing an event (outcome of interest, success) on a single trial (e.g. In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`. We need to check the cumulative probabilities, to find consecutive values for which the cumulative probabilities go from under 5% to over 5%.
