The probability of winning $2 is the probability of selecting a black ball, so it is 4/14 or 2/7.
The probability of not earning any money is the probability of an orange ball being selected, so its 2/14 or 1/7.
The probability of losing $1 is the probability of a white ball being selected, so it is 8/14 or 4/7.
