<h3>What is experimental probability?</h3>
The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.
The sample will be ={1,2,3,4,5,6,7,8,9}=9
favourable outcomes={1,3,5,7,9,}=5
The theoretical probability of spinning and odd number =
As she spends the spinner 12 times
The experimental probability =
Hence the theoretical probability =, The experimental probability =
