OpenStudy (jim766):

can the numbers be used more than once?

OpenStudy (anonymous):

i dont really know

OpenStudy (jim766):

I am guessing no... how many winning numbers will there be?

OpenStudy (jim766):

a winning number is 6 digits long. and there will only be one of them

OpenStudy (jim766):

that is what we are looking for, 1 number, that goes on top of the fraction. probability is how many times the thing we are looking for ------------------------------------- the number of possiblilities there are

OpenStudy (jim766):

so what we need to know is how many possiblilies are there for this 6 digit number. ______ _______ _______ _______ ________ _________ how many possible numbers could be in the first spot?

OpenStudy (anonymous):

5

OpenStudy (jim766):

the choices are 1 through 45 for the first spot, how many possiblities are there?

OpenStudy (jim766):

imagine there are 45 ping pong balls in a bin, each labeled with a different number, 1-45

OpenStudy (jim766):

the first time I reach in to pull out a ping pong ball, how many are there?

OpenStudy (anonymous):

1?

OpenStudy (jim766):

how many balls are in the bin?

OpenStudy (jim766):

imagine there are 45 ping pong balls in a bin, each labeled with a different number, 1-45

OpenStudy (anonymous):

So theres 45 ping pong in each bin?

OpenStudy (jim766):

there is one bin and it has 45 ping pong balls in it, each with a different number 1,2,3 ..to 45

OpenStudy (jim766):

so the first time I reach in to pull a ball out, how many possibilities are there?

OpenStudy (jim766):

there are 45 possiblities for the first one

OpenStudy (anonymous):

So , 45 ping pongs ... Each ping pong with numbers .. So 45/45?

OpenStudy (jim766):

this winning lottery number will have 6 numbers, 1-45 for the first number there are 45 possiblites for the 2nd number there are 44 possiblities, because I took one out already for the 3rd number there are 43 possiblities, because I took out two already

OpenStudy (jim766):

for the 4th number there are 42 possiblities for the 5th number threre are 41 possibilites

OpenStudy (jim766):

the last number is the mega number so, its says that goes from 1-45 so there are 45 possiblilites 45*44*43*42*41* 45 = ?

OpenStudy (jim766):

your gonna need a calculator...

OpenStudy (anonymous):

yes and i got 6597498600

OpenStudy (jim766):

there is 1 number I will accept ------------------------- 6597498600
