A dice is rolled. What is the probability of getting a number less than 4? A. 1/2 B. 1/3 C. 2/3 D. 1/6 相关知识点: 试题来源: 解析 A。解析:骰子有 6 个面,数字小于 4 的有 1、2、3 三个面,所以概率是 3/6 化简为 1/2。B、C、D 选项错误计算。
So,$P(\textrm{Sum is 10}) > P(\textrm{Sum is 11}) $.So, the probability that the sum is equal to $10$ is more likely to happen than a sum equal to $11$.Example 7: We roll two dice simultaneously. Find the probability of the following events:...
You roll a dice. What is the probability of getting a number greater than 4? A. 1/6 B. 1/3 C. 1/2 D. 2/3 相关知识点: 试题来源: 解析 B。骰子一共有 6 个面,数字大于 4 的有 5 和 6 两个,所以概率是 2÷6 = 1/3。选项 A 是单个数字出现的概率;选项 C 是错误的;选项 D ...
By using dynamic programming, we divide n dices into n stages, each stage takes different sums as different states.The current states is the sum of six previous states, representing the six values of a dice. For further optimization we can use a one-dimensional array to save and update stat...
Life is full of random events! You need to get a "feel" for them to be smart and successful. The toss of a coin, throw of a dice and lottery draws are all examples of random events. Events An "Event" can be one or more outcomes. ...

If you roll a fair dice, what is the probability of getting an odd number?A. 1/2 B. 1/3 C. 2/3 D. 1/6 相关知识点: 试题来源: 解析 A。解析:骰子有 6 个面,分别是 1、2、3、4、5、6,其中奇数有 1、3、5,共 3 个,所以掷出奇数的概率是 3÷6 = 1/2 。反馈 收藏 ...
To find the probability of rolling at least one 5, we can find the probability of not rolling a 5 and subtract that from 1, since you either roll a 5 or not roll a 5. The probability of not rolling a 5 on either dice is (56)(56)=2536. Therefore, the probability of rolling at...
Probability is the chance that something will happen. It can be shown on a line: The probability of an event occurring is somewhere between impossible and certain.As well as words, we can use numbers to show the probability of something happening:...
What is the probability of rolling doubles with a standard pair of dice?掷两粒骰子点数相同的概率是多少?答案：1：6 概率， 即 16.6666 （无论第一个骰子什么点数，第二个骰子有同样点数的概率是 1：6）
