Question

a city held a bike parade. 10 bikers rode recumbent bicycles, and 82 bikers rode other types of bicycle.
what is the probability that a randomly chosen bike in the parade was a recumbent bicycle?
write your answer as a fraction or whole number.
p(recumbent bicycle) =

Explanation:

Step1: Calculate total number of bikers

Total number of bikers = Number of recumbent bikers + Number of other - type bikers. So, \(10 + 82=92\).

Step2: Use probability formula

The probability formula is \(P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, the number of favorable outcomes (recumbent bikers) is \(10\), and the total number of outcomes (total bikers) is \(92\). So, \(P(\text{recumbent bicycle})=\frac{10}{92}\). Simplify the fraction by dividing numerator and denominator by \(2\), we get \(\frac{5}{46}\).

Answer:

\(\frac{5}{46}\)
