N the Avery Ranch area 20% of the homes are built in what is known as the Tuscan style (two story, tile roof, brick or stucco siding). So p=0.2. Out of 50 homes, what is the probability that exactly 10 are Tuscan Style?

The Answer would be 0.14

Step-by-step explanation:

If you are using a TI-83 plus or something of that sort then you can follow along

The question asks "What is the probability that exactly 10 are Tuscan Style?" The keyword here is 'exactly' this means out of the 5 formulas dealing with this you would use Binompdf(n,p,k)

To use this on your calculator do:

2nd VARS (Distr)

scroll down to ' 0:binompdf( '

then hit enter

DO NOT USE ' 1: normalpdf( 'This was my own mistake when dealing with this question.

After you hit enter you should fill out n,p,k

In this case N=50 , P=0.2 and K=10

This should give you 0.139 which is rounded to 0.14

Hope this helps!

55% are girls and 45% are boys : ) hope this
