A city held a bike parade. 52 bikers rode in the parade, and 8 of them rode a fixed-gear bicycle.

Vedmedyk [2.9K]

Answer:

$\frac{2}{13}$

Step-by-step explanation:

Find the probability by dividing the number of fixed gear bikers by the total number of bikers in the parade.

Since there are 8 fixed gear bikers and 52 bikers in total, this will be found by dividing 8 by 52.

So, the probability as a fraction is $\frac{8}{52}$

This can be simplified by dividing both the numerator and denominator by 4:

= $\frac{2}{13}$

So, the probability is $\frac{2}{13}$
