The spinner has a total of 5 equally sized sections. This means that each possible outcome has an equal probability of 1/5 (0.20 in decimal form) that the spinner lands on it. Therefore, to calculate the number of times that the spinner would most likely land on "lose a turn", we need to multiply the probability that we just mentioned by the number of times the spinner will be spun...
0.20 * 100 = 20 times
Finally, we can see that the spinner will most likely land on "lose a turn" 20 times in 100 spins.
