Solved Example on Flow Chart
Ques: The flow chart shows the probability of getting a sum, which is a multiple of 5 when two dice are rolled. If Robert gets the sum as 8, according to the flow chart, what will Robert do next?
Choices:
A. Roll the dice again.
B. He subtracts 3 from 8 to proceed.
C. He adds 2 to 8 to proceed.
D. He gets the probability as 1/2.
Correct Answer: A
Solution:
Step 1: It is given that the flow chart shows the probability of getting a sum that is a multiple of 5 (5, 10, 15..).
Step 2: Robert gets the sum as 8, which is not a multiple of 5.
Step 3: So, Robert has to roll the dice again.
