What is the probability that Martha will fly to Las Vegas all 4 instances?

Answer by Pi R Squared
Hi,

(¼)^four = 1/256

I hope that aids!!

Answer by Mike is God
4^four = 1 in 256 or .39% possibility

Answer by Merlyn
Let X be the amount of flight Martha has to vegas. X has the binomial distribution with n = 4 trials and results probability p = .25

In general, if X has the binomial distribution with n trials and a good results probability of p then
P[X = x] = n!/(x!(n-x)!) * p^x * (1-p)^(n-x)
for values of x = , 1, two, …, n
P[X = x] = for any other worth of x.

The probability mass function is derived by hunting at the amount of mixture of x objects selected 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 suggest of the binomial distribution is n * p = 1
the variance of the binomial distribution is n * p * (1 – p) = .75
the normal deviation is the square root of the variance = √ ( n * p * (1 – p)) = .8660254

The Probability Mass Function, PMF,
f(X) = P(X = x) is:

P( X = ) = .3164063
P( X = 1 ) = .421875
P( X = two ) = .2109375
P( X = 3 ) = .046875
P( X = four ) = .00390625 ← answer

I imagine there must be at least one no limit table that literally has “no limit,” bring as much money as you’ve got. It may be exclusive and you need to be a high roller to get access to it, but it’s there somewhere.
