At a particular subway station entrance, there are three gates, as shown below. All subway riders using this entrance must use one of the three gates left, middle, or right to enter the station. Based on observations over time, the probability of a rider using the middle gate is 0.24. The probability of a rider using the left gate is equal to the probability of a rider using the right gate. At this subway station entrance, the probability, to the nearest hundredth, that a randomly selected rider uses the left or middle gate to enter the station is A. B. C. D. 0.09 0.12 0.62 0.74
