题目
Alejandro has a six-sided die with faces numbered 1 through 6. He rolls the die twice.
Quantity A
The probability that both rolls are even
Quantity B
The probability that neither roll is a multiple of 3
选项
C.The two quantities are equal.
D.The relationship cannot be determined from the information given.
解析
两次掷骰子均为偶数的概率是 3/6*3/6,因为1到6中共有3个偶数(2、4、6)。两次掷骰子均不是3的倍数的概率是 4/6*4/6,因为1到6中只有2个3的倍数(3、6)。因此,比较 1/4 和 4/9,答案选B!
