sat数学的三角函数sat2的数学求三角函数的时候 一般默认的是弧度制还是角度制?BTW 帮我翻译一道题吧 我有点不太理解A coin is tossed three times.Given that at least one head appears,what is the probability that
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。
Step by step video & image solution for A coin is tossed three times, where (i) A : head on third toss,B: heads on first two tosses (ii) A: at least two heads, B : at most two heads (iii) A : at most two tails,B at least one tail In each case find P(A/B). by Math...
Step by step video & image solution for A coin is tossed three times. Find P(A/B) in each of the following: A= Head on third toss, B= Head on first two tosses A= At least two head, B= At most two heads. A= At most two tails, B= At least one tail. by Maths experts to...
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...
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...
