    p=0.70, n=7,r=5

    How do you apply this for > or < a number of results?

  • Will Oct 10, 2012

    What about for > or < a number of results? i.e. n=120, p=.02, and r>1

Hello,
Let us start with a review of the formula for the binomial distribution
f(r;n,p)=n!/(r!(n-r)!)x(p^r)x(1-p)^(n-r)

But n!/(r!(n-r)!)=(nCr) you get
f(r;n,p)= (nCr)x(p^r)x(1-p)^(n-r)

Exemple : n=25, r=6, p=0.7

f(6;25,0.7)= 25 [PRB] [-->] 6 [ x ] {0.7[ ^] 6 }[ x ]{0.3[ ^ ]19}

The arrow means a horizontal scroll once to select the (nCr) function. [ x ] stands for the multiplication sign.
[ ^] is the raise to the power key
The { } are used here as parentheses to make formula legible.

Five items are selected at random from a production line. Whiat is the probability of selecting exactly two defectives if it is known that the probability of a defective item from this production system is 0.05?

P(2)= 5! 0.05^2(1 - 0.05)^5-2
2!(5-2)!

How do you calculate Poisson Distribution?


Suppose that astronomers estimate that large meteors (above a certain size) hit the earth on average once every 100 years (lamda = 1 event per 100 years), and that the number of meteor hits follows a Poisson distribution. What is the probability of k = 4 meteors hits in the next 100 years?

Texas 30XIIB binomial cdf


The only known equation for the cumulative binomial distribution is the sum of the individual binomial probabilities. Some more sophisticated (and more expensive) calculators have that equation built in, but the 30xii does not.

If n>30 and n*p>5 and n*(1-p)>5 then you can approximate the cumulative binomial with the normal probability function, but again the 30xii does not have that built in.

I was told that, to do binomial distributions on a ti-86, I would need to hit 2nd Math, then More, and I should see something that says STAT and go from there to get to DIST and Binomi. I see nothing...


Hello,

Sorry, but you information is wrong, to find the binomial distribution use the PROB menu not the STAT menu. Its name is randBi
[2nd][MATH][F2:PROB] scroll right.
Hope it helps.

How do i enter the formula into my calc for a binomial distribution? this is for a ti-30xs multiview


Hello,
This is for the TI-30 XIIS. It should work for you once you find the (nCr) key or the menu item under PRB key. If you know the formula skip to Exemple

Let us start with a review of the formula for the binomial distribution
f(r;n,p)=n!/(r!(n-r)!)x(p^r)x(1-p)^(n-r)

But n!/(r!(n-r)!)=(nCr) you get
f(r;n,p)= (nCr)x(p^r)x(1-p)^(n-r)

Exemple : n=25, r=6, p=0.7

f(6;25,0.7)= 25 [PRB] [-->] 6 [ x ] {0.7[ ^] 6 }[ x ]{0.3[ ^ ]19}

The arrow means a horizontal scroll once to select the (nCr) function. [ x ] stands for the multiplication sign.
[ ^] is the raise to the power key
The { } are used here as parentheses to make formula legible.

Hope it helps

Error message with binopdf function


Yes, eleven million is rather extreme for the binomial distribution. For this large a value the binomial distribution is sufficiently indistinguishable from the normal approximation.
