Correct Answer
B
Explanation
To find the probability of selecting a medal that is not a gold medal, we need to calculate the number of non-gold medals and divide it by the total number of medals in the container.The number of non-gold medals is the sum of silver and bronze medals, which is 22 + 18 = 40.The total number of medals in the container is 30 + 22 + 18 = 70.Therefore, the probability of selecting a medal that is not a gold medal is 40/70, which simplifies to 4/7.
