Q. At a science museum, visitors can compete to see who has a faster reaction time. Competitors watch a red screen, and the moment they see it turn from red to green, they push a button. The machine records their reaction times and also asks competitors to report their gender.\begin{tabular}{|l|c|c|}\cline { 2 - 3 } & Male & Female \\\hline Less than 0.3 seconds & 3 & 5 \\\hline 0.3 to 0.7 seconds & 5 & 2 \\\hline\end{tabular}What is the probability that a randomly selected competitor reacted in less than 0.3 seconds and was female?Simplify any fractions.□
Calculate Total Competitors: First, let's find the total number of competitors. We add up all the males and females in both reaction time categories.Total competitors = (3 males with <0.3s) + (5 females with <0.3s) + (5 males with 0.3−0.7s) + (2 females with 0.3−0.7s)Total competitors = 3+5+5+2Total competitors = 15
Find Females with <0.3s Reaction Time: Now, we need to find the number of competitors who are female and reacted in less than 0.3 seconds.Number of females with <0.3s reaction time = 5
Calculate Probability: To find the probability, we divide the number of females with <0.3s reaction time by the total number of competitors.Probability = Number of females with <0.3s reaction time / Total competitorsProbability = 155
Simplify Fraction: Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 5.Probability = (5÷5)/(15÷5)Probability = 1/3
