Studdy Solution
For the spinner with 20 numbers and a range of 1, the probability is 220=110\frac{2}{20} = \frac{1}{10} near the edges and 320\frac{3}{20} elsewhere.
Following the same steps, for a spinner with 10 numbers and a range of 2, the probability is 510=12\frac{5}{10} = \frac{1}{2}.
For a spinner with 30 numbers and a range of 3, the probability is 730\frac{7}{30}.
For a spinner with 10 numbers and a range of 4, the probability is 910\frac{9}{10}.
For a spinner with 10 numbers and a range of 5, the probability is 1010=1\frac{10}{10} = 1.
For a spinner with 20 numbers and a range of 6, the probability is 1320\frac{13}{20}.
For a spinner with 100 numbers and a range of 18, the probability is 37100\frac{37}{100}.
