A spinner with 5 equally sized slices has 2 red slices, 2 yellow slices, and 1 blue slice. Keiko spun the dial 1000 times and got the following results. From Keiko's results, compute the experimental probability of landing on yellow

Sagot :

Probability is expressed as

number of favorable outcomes/number of total outcomes

But probability can also be classified as theoretical probability and experimental probability. The theoretical probability is the normal probability of each outcome while the expreimental probability is the probability of an outcome given that trials have been made.

In this scenario,

total number of trials = 400 + 195 + 405 = 1000

favorable outcomes = number of times that we landed on yellow = 405

the experimental probability of landing on yellow is

405/1000 = 0.405
