a) The experimental probability of rolling a 4 is 40%
What is experimental probability ?
Probability, in which we get repeated trials of an experiment is called experimental probability.
Experimental Probability = (Number of times the event occurs)/(Total number of trials)
What is the required probability ?
Let, Experimental probability of rolling a 4 = P(A)
∴ P(A) = (no. of times rolling a 4)/(total number of rolling)
= [tex]\frac{8}{20}[/tex]
= [tex](\frac{8}{20}[/tex]×[tex]100)[/tex] %
= 40%
