Suppose there is only one ticketing counter at cinema A. The number of customers buying tickets at this counter per minute can be modeled by a Poisson distribution with a mean of 2.8. The probability distribution of the number of tickets bought by a customer at this ticketing counter is shown in the following table:

Number of tickets bought 1 2 3 4 5

Probability 0.3 0.6 0.04 0.03 0.03

Q. Given that fewer than 3 customers buy tickets at the ticketing counter in a certain minute, find the probability that only 1 ticket is bought in total.
