You randomly draw a marble from a bag, record is color, and then replace it. You draw a blue marble 11 out of 50 times. What is
the experimental probability that the nes marble will be blue? Write your answer as a fraction, de mal, or percent. The experimental probabilty that the next marble will be blue is
This may seem like a trick question, but it's not. Your teacher simply wants to know how many times you got blue out of the number of times total. The numerator is the number of blue. The denominator is the number of total tries. The fraction 11/50 cannot be reduced because 11 and 50 share no common factors other than 1.
Notes:
11/50 = 0.22 = 22%
The answer above applies to experimental probability only. The theoretical probability is likely different. We don't have enough info to compute the theoretical probability.
