What is the probability that MRA will make at least $100,000 (round to 2 decimals)?

Question

The following table is a partial probability distribution for the MRA Company’s projected profits ( profit in  s) for the first year of operation (the negative value denotes a loss).

(x): f(x)

-100 .10

0 .21

50 .28

100 .25

150 .12

200 .04

Answer 1

If am reading the data correctly f(x) is the probability of a particular income.

That would mean that the probability of making at least $100,000, would be the sum of the probability of making $100,000, $150,000 and $200.000 (0.25 + 0.12 + 0.04 = 0.41 or 41%)
