**Probability**

With a fair coin the probability of a given 7-flip series is equal to ANY 7-flip series. That is, P(HHHHTTT) = P(TTTHHHH) = P(THTHTHT).... There are 2^7 = 128 possible 7-filp series. This is the denominator. There are 4-choose-7 ways to have a 4 heads in 7 filps. 4-choose-7 is...

a. I don't know what X signifies. b. First find the probability of two aces, then 3 non-aces. (4/52)(3/51)(48/50)(47/49)(46/48) = ? c, d. Use similar to process above. e. At least one ace = 1, 2, 3, or 4 aces. Use answers from b and c, plus calculate probability of 3 aces and ...

**Math**

To carry that a bit further odds = probability of what you want / probability of what you do not want you want odds against A so probability of what you want is 35/36 and the probability of what you do not want is A or 1/36 so odds against A are (35/36) / (1/36) = 35 to 1 ...

**Data management**

for the second part it is a particular bathroom of the 6 The probability that this bathroom is not cleaned each day is 5/6 after n days the probability is (5/6)^n how many days until the probability is like 1/2 ? 1/2 = (5/6)^n log .5 = n log (5/6) -.301 = n (-.07918) n = 3.8 ...

**Statistics**

Suppose that the probability distribution of a random variable x can be described by the formula P(x) = x/15 For each of the values x = 1, 2, 3, 4, and 5. For examples, then, p(x=2) = p(2) = 2/15 a Write out the probability distribution of x. b Show that the probability ...
