For the discrete distribution, we need sum of all probabilities to be 1 and each probability value should be in range [0,1]. here the sum is 0.90, which i less than 1, so this is NO, BECAUSE THE TOTAL PROBABILITY IS NOT EQUAL TO 1.

The mean waiting time at the drive-through of a fast-food restaurant from the time an order is placed to the time the order is received is 84.4 seconds. A manager devises a new drive-through system that she believes will decrease wait time. As a test, she initiates the new system at her restaurant and measures the wait time for 10 randomly selected orders. The wait times are provided...
