For a standard normal distribution, find: P(Z > 1.86) HINT: Recall that for spreadsheet programs like Excel or LibreOffice. org, you can use =normdist(x, mean, stdev, 1) to find cumulative normal probabilities. If you wanted to find the probability between two values x_1 and x_2, you could subtract the smaller cumulative probability from the larger: =normdist(x_2, mean, stdev, 1) - normdist(x_1, mean, stdev, 1)
