Q. Trevor gets 1010 heads when flipping a weighted coin 1818 times. What is the experimental probability that the next flip will come up heads? Simplify your answer and write it as a fraction or whole number.\newlineP(heads)=___P(\text{heads}) = \_\_\_
  1. Calculate Experimental Probability: The experimental probability is calculated by dividing the number of successful outcomes by the total number of trials. In this case, the number of successful outcomes is the number of times Trevor got heads, which is 1010, and the total number of trials is the number of times he flipped the coin, which is 1818.\newlineCalculation: P(heads)=Number of headsTotal flips=1018P(\text{heads}) = \frac{\text{Number of heads}}{\text{Total flips}} = \frac{10}{18}
  2. Find Greatest Common Divisor: To simplify the fraction, we look for the greatest common divisor (GCD) of the numerator (1010) and the denominator (1818). The GCD of 1010 and 1818 is 22.\newlineCalculation: Simplify 1018\frac{10}{18} by dividing both the numerator and the denominator by 22.\newline1018=(10÷218÷2)=59\frac{10}{18} = \left(\frac{10 \div 2}{18 \div 2}\right) = \frac{5}{9}
