Alisha conducted an experiment in which a spinner landed on green 7 times. if the experimental probability of the spinner landing on green is 1/5, how many trials did alisha perform?

Probability = Favorable Outcome / Total Outcome

Here, P = 1/5
Favorable Outcome = 7

Substitute their values, 
1/5 = 7 / Total Outcomes
Total Trails = 7 * 5 = 35

In short, Your Answer would be: 35

Hope this helps!

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
