Question

Alicia conducted an experiment in which a spinner landed on green seven times if the experimental probability of the spinner landing on green is 1/5 how many trials did Alicia perform

Answer 1

35 trials

Explanation:

Probability = Favorable Outcome / Total Outcome

P = 1/5

Favorable Outcome = 7

Substitute the values,

1/5 = 7 / Total Outcomes

1/5 =7/x

Cross multiplication:

1x=5*7

x=35

Total Trials = 35
