To find the experimental probability of picking a red ball from bowl A, we need to calculate the total number of balls selected from bowl A and then find the proportion of red balls selected.
From Simon's results:
- Total balls selected from bowl A: 5 white + 15 red = 20 balls
- Number of red balls selected from bowl A: 15 red balls
Experimental probability of picking a red ball from bowl A:
= Number of red balls selected from bowl A / Total balls selected from bowl A
= 15 red balls / 20 total balls
= 0.75
To convert this to a percentage, multiply by 100:
= 0.75 * 100
= 75%
Therefore, the experimental probability of picking a red ball from bowl A is 75%.
Bulls 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 boil a? The answer needs to be in percent form. Bowl A five white ball selected, bowl be 16 white balls selected, bowl A 15 Red balls selected bowl B 4 red balls selected
