Emilio spins a spinner that is divided into 8 equal sectors numbered 1 through 8. in his first three spins, the spinner lands on 8. what is the experimental probability that emilio will spin a 10 on his fourth spin?

Your probability is zero for two reasons.
  1) The experimental probability of landing on 8 is 100%
  2) There is no 10.

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for

The answers are 20,30,80,180,960,890,1230,4560. on the first row
