3. A bag contains five different lightbulbs. The bulbs are the same size but each has a different wattage. If you select three bulbs at a random,how many different outcomes will be in the sample space if the bulbs are selected without replacement?
I understand there is 5 different light bulbs, I tried to doing a tree diagraphm, but my answer was wrong and I am not sure if I am going in the right direction, the books answer is 4000. Could you explain to me how they got that answer.
