Final answer:
To find the probability that the sum of the numbers is greater than 4, we need to find all the possible outcomes where the sum is greater than 4 and divide it by the total number of possible outcomes. The probability is 0.5.
Step-by-step explanation:
To find the probability that the sum of the numbers is greater than 4, we need to find all the possible outcomes where the sum is greater than 4 and divide it by the total number of possible outcomes.
The possible outcomes where the sum of the numbers is greater than 4 are (2,3), (2,4), (3,2), (3,4), and (4,2), (4,3), which is a total of 6 outcomes. The total number of possible outcomes is 4 x 3 = 12, since there are 4 marbles and 3 marbles left after the first marble is drawn.
Therefore, the probability is 6/12 = 0.5
