A bag contains 6 slips of paper numbers 1 through 6. An experiment consists of drawing 2 slips of paper simultaneously from the bag. What is the probability the two numbers will add up to less than 4?
@spectrum @jhonyy9 @hero @gucchi
your answer is 2/5 because you combine the first cards (6,2) (2,6) (5,3) (3,5) (4,4) – only 5 possible scenarios for sum to be 8. One from this 5 has already happened. Notice here that the case of (6,2) is different from (2,6), and similarly the case of (5,3) is different from (3,5). From this five cases, only in two we have 5. So, the probability is 2 chances out of 5 that the one that occurred had 5: P=2/5.
