In a random selection problem involving 50 units with a random number of 0.19, which unit is selected?

To determine which unit is selected based on a random number in a probability problem, one typically applies the random number to the total number of units available. In this case, there are 50 units, and the random number provided is 0.19.

To find out which unit corresponds to this random number, you multiply the total number of units (50) by the random number (0.19). The calculation would be:

50 units × 0.19 = 9.5.

Since selectees must be whole units and rounding is usually applied in this context, rounding 9.5 to the nearest whole number gives you 10. Thus, the 10th unit would be selected.

This process shows how mathematical concepts related to probability and selection can be applied in systematic ways to arrive at a clear choice, confirming that the 10th unit corresponds to the result derived from the random selection criteria.
