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。
The formula to calculate the probability of an event is as follows.Probability(Event) = Favorable Outcomes/Total Outcomes = x/nProbability 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...
Let be the event of drawing a diamond card in the first draw and be the event of drawn a diamond card in the second draw. Then, After drawing a diamond card in first draw 51 cards are left out of which 12 cards are diamond cards. and Probability of drawing a diamond card in second...
What is the joint probability of drawing a number ten card that is black? Event “A” = The probability of drawing a 10 = 4/52 = 0.0769 Event “B” = The probability of drawing a black card = 26/52 = 0.50 Therefore, the joint probability of event “A” and “B” is P(4/52)...

What is the probability of drawing a black card or a ten in a deck of cards? There are 4 tens in a deck of cards P(10) = 4/52 There are 26 black cards P(black) = 26/52 There are 2 black tens P(black and 10) = 2/52 ...
drawn was a ten, there are now only three tens, not four, left in the deck, so the desired number is 3. Likewise, there are 51 cards, not 52, left in the deck, so the total is 51. Thus, the probability of drawing a ten given that the first card drawn was a ten is351...
The probability of anything but A occurring would be P(A′). So, the complement of drawing a face card from the deck would be drawing a numbered card. The probabilities of an event and its complement always add up to 1, or 100%, because the event either occurs or it does not. ...
