To solve this problem, we need to calculate the probability that the arrow will stop on either section 2 or section 5.Step 1: Determine the total number of sections on the disc.According to the picture details, the disc is divided into 10 equal parts.Step 2: Identify the favorable outcomes.The favorable outcomes are the sections labeled with the numbers we are interested in, which are 2 and 5.Step 3: Count the number of sections labeled with 2 and 5.From the picture details, we know that there is one section labeled with the number 2 and one section labeled with the number 5.Step 4: Calculate the probability.The probability (P) of an event is calculated using the formula:
In this case, the probability that the arrow will stop on section 2 or section 5 is:
We have 1 section labeled 2 and 1 section labeled 5, so there are 2 favorable outcomes.
Step 5: Simplify the fraction and convert to a percentage.
To convert this to a percentage, we multiply by 100:
Answer:B.
