Q. Suzie is shopping for a new bicycle. She is most interested in color and type of tires.\begin{tabular}{|l|c|c|}\hline & Red & Green \\\hline Road bike tires & 5 & 9 \\\hline Mountain bike tires & 6 & 7 \\\hline City bike tires & 8 & 7 \\\hline\end{tabular}What is the probability that a randomly selected bike does not have mountain bike tires and is not red?Simplify any fractions.□
Total Bikes Calculation: Total number of bikes = 5 (Red Road) + 9 (Green Road) + 6 (Red Mountain) + 7 (Green Mountain) + 8 (Red City) + 7 (Green City) = 42 bikes.
Non-Red Bikes Count: Number of bikes that are not red = 9 (Green Road) + 7 (Green Mountain) + 7 (Green City) = 23 bikes.
Non-Mountain Tires Count: Number of bikes that do not have mountain bike tires = 5 (Red Road) + 9 (Green Road) + 8 (Red City) + 7 (Green City) = 29 bikes.
Non-Red Non-Mountain Bikes Count: Number of bikes that are not red and do not have mountain bike tires = 9 (Green Road) + 7 (Green City) = 16 bikes.
Probability Calculation: Probability = Total number of bikesNumber of bikes that are not red and do not have mountain bike tires = 4216.
Fraction Simplification: Simplify the fraction 4216 by dividing both numerator and denominator by 2=218.
