So we’re going to base our experimental probability on this video HERE
So we have a spinner:
The way I’m doing this problem is I am taking a spinner like this at home and I’m spinning it 10 times. I am putting a tally next to the number to see how many times I got the result.
So I will write the probabilities with the denominator as 10 and the numerator as what the result of the number is.
1 = 3/10
3= 4/10 = 2/5
4= 2/10 = 1/5
So the probability of getting a 4 is 1/5.
If I wanted to know the probability of getting anything under a 3 would be
3/10 + 1/10 = 4/10 = 2/5
