Again, assume that on 50 % of days Camila rides her bike, and on 20 % of days Camila goes running. However, this time, treat running and biking as independent events. Part A: Complete the following table using 100 randomly selected days. Use the fact that running and biking are independent to help you complete the table. Recall that if events A and B are independent, then P ( A and B ) = P ( A ) P ( B ) . Bikes Does not bike Total Runs 80 20 100 Does not run 50 Total 130 100 Part B: Calculate the probability of Camila running OR biking on a randomly selected day. Round to the nearest hundredth. Part C: Given that Camila has already gone on a bike ride, calculate the probability that she goes running. Round to the nearest hundredth
