The question is not complete. It should read;
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
Answers
a) 0.35
b)Blue
Step-by-step explanation
The probability of an event is its chance to occur.
Probability is found by the formula,
Probability = (Number of favourable outcome)/(Number of total outcome)
Part a
The orange are 21 and the total spins are 60.
Probability (orange) = 21/60
= 0.35
Part 2
The theoretical probability of blue is normally 25%.
By calculating the experimental probability of blue we get,
P(blue) = 15/60
= 1/4
In percentage
1/4×100 = 25%
So, the color that had an experimental probability that matched its theoretical probability is blue.
