3/4

it depends on how many flights she works. if it is just one flight then there is a 3/4 probability of not going to Vegas if two flights then (3/4)^2 probability of not going to Vegas for n flights the probability of (3/4) ^ n

Yes you can. However they do have restricions on how much. Off hand I dont know for sure, but its quite a bit. Your airline could tell you for sure.
2 :
Up to 4 liters if yu are over 21. See site below.
3 :
Texas residents, 21 years or older, may bring back one liter of alcohol, one liter of beer and one liter of wine once every 30 days. Residents of other states, 21 years or older, may bring back up to four liters of alcohol and one case of beer once every 30 days. Anything over these amounts is subject to customs duty and internal revenue tax. that's what the above link says! As you are coming in to Dallas--one liter it is!

Hi, (¼)^4 = 1/256 I hope that helps!! :-)

4^4 = 1 in 256 or 0.39% chance

Let X be the number of flight Martha has to vegas. X has the binomial distribution with n = 4 trials and success probability p = 0.25 In general, if X has the binomial distribution with n trials and a success probability of p then P[X = x] = n!/(x!(n-x)!) * p^x * (1-p)^(n-x) for values of x = 0, 1, 2, ..., n P[X = x] = 0 for any other value of x. The probability mass function is derived by looking at the number of combination of x objects chosen from n objects and then a total of x success and n - x failures. Or, in other words, the binomial is the sum of n independent and identically distributed Bernoulli trials. X ~ Binomial( n , p ) the mean of the binomial distribution is n * p = 1 the variance of the binomial distribution is n * p * (1 - p) = 0.75 the standard deviation is the square root of the variance = √ ( n * p * (1 - p)) = 0.8660254 The Probability Mass Function, PMF, f(X) = P(X = x) is: P( X = 0 ) = 0.3164063 P( X = 1 ) = 0.421875 P( X = 2 ) = 0.2109375 P( X = 3 ) = 0.046875 P( X = 4 ) = 0.00390625 ← answer
