The probability of being correct on one day is 0.85. The forecast for each day is separate and independent of the other daily forecasts. Therefore the compound event, correct predictions 4 days in a row, is the product of the separate probabilities of being correct for each of the 4 days. P(correct 4 days) = 0.85 * 0.85 * 0.85 * 0.85. Can you calculate the probability and convert to a percentage ?
ehh i might need some help with that
