In a convenient store, the number of tellers (X) busy with customers at 12:00 noon varies from day to day. Past records indicate that the probability distribution of X is as follows: Number of Tellers (X) P(X) 0 0.029 1 0.049 2 0.078 3 0.155 4 0.212 5 0.262 6 0.215 a. What is the probability that fewer than 5 tellers are busy at 12:00 noon? b. What is the mean, variance, and standard deviation of the given data? Use three decimals.
