You would expect the arrow to land on an even number about 25% of the time.
Step-by-step explanation:
In the sector labeled 1 you would expect it to land on it 50% of the time because that sector takes up 50% of the spinner. For the rest of the sectors, you would take to the remaining 50% and divide it by four for the four other sectors on the spinner. 50 ÷ 4 = 12.5 Then you would take the number of even numbers there are on the spinner, which is two in the case, and add those percentages together. 12.5 + 12.5 = 25
