Solve it correctly please. I will rate accordingly 

It is believed that a button can be pressed an average of 10000 times until it fails, where its lifetime varies according to a Geametria
distribution with probability p of failing in any press. From a sample of 32 buttons, it was found that the average lifetime was
approximately 6000 presses.
Using the maximum likelihood estimate, p, and the hypothesised value, Po, compute the value of 2 E(p) – l(po)-
7.09
(Provide your answer to two decimal places.)
