There are 5 cards numbered from 1 to 5. What is the probability of drawing a card with number 3? A. 1/5 B. 2/5 C. 3/5 D. 4/5 相关知识点: 试题来源: 解析 A。解析:总共有 5 张卡片,抽到数字 3 的卡片只有 1 张,所以概率是 1/5。B、C、D 选项错误计算抽到特定卡片的概率。
A full deck of 52 cards contains 13 cards from each of the four suits. The probability of drawing a heart from a full deck is 1/4. Therefore, the probability of “not heart” is 3/4. P(at least three draws to win)= 1 –P(win in two or fewer draws) ...
Probability is used to predict the outcomes for the tossing of coins, rolling of dice, or drawing a card from a pack of playing cards. The probability is classified into two types: Theoretical probability Experimental probability To understand each of these types, click on the respective links. ...

Event “B” = The probability of getting a tail in the second coin toss is 1/2 = 0.5. Therefore, the joint probability of event “A” and “B” is P(1/2) x P(1/2) = 0.25 =25%. Example 3 What is the joint probability of drawing a number ten card that is black?
When drawing 5-cards from a well-shuffled, standard deck of cards, what is the probability of drawing 3 diamonds, with and without replacement? What is the probability that one card selected from a deck of 52 cards will be a spade or num...
When rolling 3 dice, what is the probability that you have number 4 on all three dice? What is the probability of drawing two clubs in two blind draws from a standard deck of cards without replacement? What is the probability that a 9-card hand has at least one 4 of a kind? A fair...
For example, the probability of drawing a red card from a deck of cards is 1/2 = 0.5. This means there is an equal chance of drawing a red and black card since there are 26 of each in a deck. As such, there is a 50-50 probability of drawing a red card versus a black card....
