- A.
24
- B.
36
- C.
48
- D.
60
- E.
72
Correct Answer
B. 36Explanation
There are 5 choices for the first digit (2, 3, 4, 5, or 6) and 4 choices for the second digit (any of the remaining 4 digits). For the third digit, there are 3 choices (any of the remaining 3 digits). Therefore, the total number of even 3-digit numbers without repeating digits formed from the digits 2, 3, 4, 5, and 6 is 5 * 4 * 3 = 60. However, since we are looking for even numbers, we need to divide by 2. So the answer is 60 / 2 = 30.Rate this question:

B. 0,165Explanation
The probability of Aji not passing the exam is 0.45, and the probability of Budi not passing the exam is 0.30. To find the probability of both Aji and Budi not passing the exam, we multiply their individual probabilities. Therefore, the probability of Aji and Budi not passing the exam is 0.45 * 0.30 = 0.135.Rate this question:

- C.
6
- D.

- E.
4
Correct Answer
A. 8Explanation
The original data set must have consisted of numbers smaller than 11 in order for the average to be 11. When a new number, 29, is added to the data set, it increases the average to 13. Since the new number is larger than the average, it must be larger than all the other numbers in the data set. Therefore, the original data set must have consisted of numbers smaller than 29, with the largest number being 8.Rate this question:
