Given that A and B are independent events, (e) fnd the value of q 10. The mmber of customers entering a certain branch of a bank on a Monday lunchtime may be modelled by a Poisson distribation with mean 2.4 per minute 4) Find the probability that, during a particular minute, four or more customers enter the branch. The probability that a customer, who enters the branch, intends to open a new account is 0.002 and is independent of the ntentions of other customers. During a particular morning 450 customers enter the bank. b) Use a suitsble approximation to find the probability that three or fewer of these 450 customers intend to open new sccounts
