A coin is tossed 4 times. The probability that at least one head turns up, is a. 116 b. 216 c. 1416 d. 1516 View Solution A coin is tossed 7 times, Then probability that at least 4 consecutive heads appear is View Solution ...
A coin is tossed four times. Each time the result H for heads or T for tails is recorded. An outcome of HHTT means that heads were obtained on the first two tosses and tails on the second two. Assume that heads and tails are equa...
The probability that the result is 5 tails in a row would be 12×12×12×12×12=132 . Thus, the probability that the result is at least one head would be 1−132=3132 .结果一 题目 A coin is tossed five times. What is the probability that the result has at least one heads? 答案...

A bag contains 14 coins of which two are counter feet with heads on the both sides,the rest are fair coins.One is selected at random from the bag and tossed,find the probability of getting a head is- View Solution A fair coin is tossed 4 times. The probability that heads exceed tails...
一枚硬币掷3次,每次都有正反两种可能,所以总共有2^3=8种可能的结果。 第二步,我们计算至少有2次连续正面朝上的结果数。这种情况有3种可能:正正反、正正正、反正正。 第三步,我们根据条件概率的公式,计算至少有2次连续正面朝上的概率。概率等于满足条件的结果数除以总的结果数,即3/8。
In an experiment of tossing a coin, if the coin is tossed 100 times and the head appears 45 times. What is the probability of getting a tail? A. 0.45 B. 0.55 C. 0.5 D. 1 相关知识点: 试题来源: 解析 B。解析:共抛 100 次,出现正面 45 次,则出现反面的次数为 100 - 45 = 55 ...
If a coin is tossed three times, and a statistician predicts that the probability of obtaining three heads in a row is 0.125, which of the following assumptions is irrelevant to his prediction? A. The s are dependent. B. The s are independent. C. The coin is unbiased. D. All of the...
