Answer:
$ -11.61
Step-by-step explanation:
The expected value in this case would be the subtraction between the probability that the draw will win for its value (the prize + value of the ticket) and the value of the ticket for the probability of not winning the draw, thus:
(1/810) * (1100 + 13) - (809/810) * (13)
1,374 -12,984 = -11.61
which means that the expected value is $ -11.61
Hence, B. Keep increasing is the best answer
