Lisa and bart spin this spinner 60 times the result are below/ black=17 blue=15 orange=21 purple=7 a. what is the experimental probability of a spin of orange? b which color had an experimental probability that matched its theoretical probability

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
