A computer is used to randomly select a number between 1 and 2000. Event A is selecting 460.
To calculate the probability of event A happening, we need to determine the total number of possible outcomes and the number of favorable outcomes.
In this case, the computer randomly selects a number between 1 and 2000. So, there are 2000 possible outcomes.
Since event A is selecting the number 460, there is only 1 favorable outcome.
To calculate the probability, we divide the number of favorable outcomes (1) by the total number of possible outcomes (2000):
Probability of event A = Number of favorable outcomes / Total number of possible outcomes
= 1 / 2000
= 0.0005 or 0.05%
Therefore, the probability of event A happening, which is selecting the number 460, is 0.0005 or 0.05%.
