The experiment testing flies for the ability to learn to fly toward the smell of potato is repeated three times. In the first experiment the first fly to succeed is the 13th, in the second experiment it is the 8th, and in the third experiment it is the 12th. Compare with the likelihood of q = 0.1.
Find the likelihood as a function of the parameter q of a geometric distribution, find the maximum likelihood estimator, and evaluate the likelihood at the maximum and at the other given value of q.
