In a certain town, 25% of people commute to work by bicycle. If a person is selected randomly from the town, what are the odds against selecting someone who commutes by bibycle? A). 3:1 B). 3:4 C). 1:3 D). 4:1
3:1
About 35% of the population has blue eyes (based on a study at Indiana University).
If someone is randomly selected, what is the probability that he or she does not have blue eyes/
To find the odds against selecting someone who commutes by bicycle, we first need to determine the proportion of people who do not commute by bicycle.
Since 25% of people commute by bicycle, the remaining percentage of people who do not commute by bicycle can be calculated by subtracting 25% from 100% (the total population).
100% - 25% = 75%
Therefore, 75% of people do not commute by bicycle.
The odds against selecting someone who commutes by bicycle can be expressed as a ratio of the number of people who do not commute by bicycle to the number of people who do commute by bicycle.
In this case, the odds against selecting someone who commutes by bicycle are:
75% : 25%
Simplifying the ratio, we get:
3 : 1
Therefore, the odds against selecting someone who commutes by bicycle are 3:1, which corresponds to option A) in the given choices.
