A colored marble is to be chosen at random from a bag of marbles. The probability that the marble chosen will be green is 4/Which of the following numbers could NOT be the total number of marbles in the bag? Select
all
such numbers.
选项
A、64
B、72
C、110
答案
A, C
解析
The correct answer is A and C. You are given that the probability of drawing a green marble is 4/9 or 4 out of 9. This means that the total number of marbles in the bag must be a multiple of 9. The question asks for the answer choice that cannot be the number of marbles in the bag. Therefore, the answer choice that is not a multiple of 9 will be the correct answer. Neither 64 nor 110 are multiples of 9.
