Forecasting the weather. Here’s a simple use of probability in real life that you likely already do. We always check the weather forecast before we plan a big outing. Sometimes the forecaster declares that there’s a 60 percent chance of rain. We might decide to delay our outing because we trust this forecast.

WebbExample 1: Find the probability of getting a number less than 5 when a dice is rolled by using the probability formula. Solution To find: Probability of getting a number less than 5 Given: Sample space = {1,2,3,4,5,6} Getting a number less than 5 = {1,2,3,4} Therefore, n (S) = 6 n (A) = 4 Using Probability Formula, P (A) = (n (A))/ (n (s)) WebbTherefore, the theoretical probability is 1 2. Alternatively, Beau could flip the coin 6 times. Suppose he sees heads 2 times and tails 4 times. Then the relative frequency in his sample is 2 6 or 1 3. In this case, the observed relative frequency does not match the theoretical relative frequency. WebbTheoretical Probability = Number of favorable outcomes / Number of possible outcomes. Number of favorable outcomes = 5 Number of possible outcomes = 5 + 7 = 12 P (red) = … csiro phd top up scholarships
