Sagot :
Using the concept of probability, the probability that the first disk selected has a smaller number than the second is 0.381
Disk marked 11 = 4
Disk marked 22 = 6
Disk marked 33 = 7
Disk marked 44 = 3
Total disks = 20
Recall :
- Probability = required outcome /Total possible outcomes
Ways of making selection such that first disk is smaller than second :
First = 11 and second = 22 = (4/20 × 6/19) = 0.0631
First = 11 and second = 33 = (4/20 × 7/19) = 0.0736
First = 11 and second = 44 = (4/20 × 3/19) = 0.0316
First = 22 and second = 33 = (6/20 × 7/19) = 0.1105
First = 22 and second = 44 = (6/20 × 3/19) = 0.0474
First = 33 and second = 44 = (7/20 × 3/19) = 0.0553
Hence,
P(first disk < second) = (0.0631 + 0.0736 + 0.0316 + 0.1105 + 0.0474 + 0.0573) = 0.381
Therefore, probability that the first disk selected is smaller than the second will be 0.381
