What is the probability that a randomly selected individual reports a high level of usage?
Given,
Low | Moderate | High | Total | |
18 - 30 | 286 | 592 | 464 | 1342 |
31-35 | 209 | 438 | 381 | 1028 |
56+ | 254 | 237 | 139 | 630 |
Total | 749 | 1267 | 984 | 3000 |
Low | Moderate | High | |
18 - 30 | 286/3000 = 0.0953 | 592/3000 = 0.1973 | 464/3000 = 0.1546 |
31-35 | 209/3000 = 0.0696 | 438/3000 = 0.146 | 381/3000 = 0.127 |
56+ | 254/3000 = 0.0846 | 237/3000 = 0.079 | 139/3000 = 0.0463 |
The probability that a randomly selected individual reports a high level of usage = 0.154+0.127+0.0463
= 0.3273
The probability that a randomly selected individual reports a high level of usage is 0.3273.
