Detailed Solution

155. d: The probability of tossing heads is based on frequencies obtained in an experiment.

156. b: Find the number of times an 8 was spun during the experiment i.e, 13 out of 100

157. a: 9/10 is close to 1.

158. c: The area of the whole dartboard is 25 square units. 15/25 = 3/5
