pls. do show me the solution

OpenStudy (ranga):

There are 5 equal possibilities for the arrow to land on. We are interested in two of them: either "lose a turn" or "back 2" The probability of getting either of those two is: desired outcome / total possibilities = 2/5 If you spin 60 times, the number of times you will get either is 60 * 2/5 = 24

OpenStudy (anonymous):

so the the answer is 24 right

yes.
