a) Work out the estimated robability of the spinner landing o orange using i) Joshua's results. ii) Alice's results. Give each of your answers as a fraction in its simplest form. b) Which person's results give a better estimate for the probability Write a sentence to explain your answer.

To determine the estimated probability of the spinner landing on orange using Joshua's results, you would divide the number of times the spinner landed on orange by the total number of spins he conducted. For Alice, you would do the same with her results. This will yield two fractions that can be simplified to their lowest terms. When comparing the two estimates, the person with the largest number of spins usually provides a more reliable estimate of probability since it tends to average out anomalies, leading to a more accurate representation of likelihood. Therefore, if Joshua spun the spinner more times than Alice, his estimate would likely be better; otherwise, Alice's would take the lead!
