Q. A bag was filled with colored items. Rob repeatedly drew one at random, then replaced it. He did this 2020 times. Here are the results:\newlineColored Item Experiment\newline\begin{tabular}{|c|c|}\newline\hline Color & Times \\\newline\hline green & 33 \\\newline\hline golden & 44 \\\newline\hline white & 22 \\\newline\hline black & 22 \\\newline\hline blue & 44 \\\newline\hline yellow & 55 \\\newline\hline\newline\end{tabular}\newlineWhat is the experimental probability of drawing a pink item? Write your answer as a fraction.
  1. Rob's Drawing Attempts: Rob drew items 2020 times and none were pink, so the number of times a pink item was drawn is 00.
  2. Calculating Experimental Probability: To find the experimental probability, we divide the number of times the event (drawing a pink item) occurred by the total number of trials.
  3. Calculating Experimental Probability: So, the experimental probability of drawing a pink item is 00 (times pink was drawn) divided by 2020 (total draws).
  4. Result: Experimental Probability: 0÷20=00 \div 20 = 0, so the experimental probability of drawing a pink item is 00.
