Number of White Balls Selected 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.
a 25%
b 78.95%
c 37.5%
d 75%
The total number of times Simon selected a ball from both bowls is 20 (5+15=20 and 16+4=20). Out of those 20 times, Simon picked a red ball from Bowl A 15 times. Therefore, the experimental probability of picking a red ball from Bowl A is 15/20, which simplifies to 3/4 or 0.75. In percentage form, this is 75%.
The answer is d) 75%.
To find the experimental probability of picking a red ball from Bowl A, we need to divide the number of red balls selected from Bowl A by the total number of balls selected from Bowl A.
The number of red balls selected from Bowl A is 15.
The total number of balls selected from Bowl A is 5 + 15 = 20.
So, the experimental probability of picking a red ball from Bowl A is 15/20 = 0.75.
To convert this to a percentage, we multiply by 100.
0.75 * 100 = 75%
Therefore, the answer is d) 75%
