To find the experimental probability of picking a red ball from Bowl A, we need to add up the number of times a red ball was selected from Bowl A and divide it by the total number of times a ball was selected from Bowl A.
From the table, we see that Bowl A was selected 20 times and a red ball was picked 15 times.
Experimental probability = (Number of red balls select from Bowl A) / (Total number of balls selected from Bowl A)
Experimental probability = 15 / 20 = 0.75
Converting to percentage form:
0.75 * 100% = 75%
Therefore, the experimental probability of picking a red ball from Bowl A is 75%.
The correct answer is:
• 75%
Bowl A Number of white balls selected Bowl B number of red balls selected
Bowl A | 5 | 15 |
Bowl B | 16 | 4 |
Bowls A and B contain a number of white and red balls. Simon repeatedly selected a ball from both bowls and recorded the results in a table. Using Simon's results, what is the experimental probability of picking a red ball from Bowl A? The answer needs to be in percent form.
• 75%
• 78.95%
• 37.5%
• 25 %
