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...
3132 . 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 hea...

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。
