Question

A jar contains marbles numbered 1, 2, 3, and 4. Two marbles are

drawn randomly and without replacement.
Find P(the sum of the numbers is greater than 4)
Enter your answer as a decimal rounded accurate

Answer 1

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
