anonymous 5 years ago (NOBODY CAN SEEM TO HELP ME WITH THIS) To play the cali lottery a person has to select 6 out of the 51 numbers.Paying 1 dollar for each 6 number selection. If you pick 6 numbers that are the same as the ones drawn by the lottery you win.What is the probabity that a person with 1 combination of six numbers will win ? What is the probabilty of winning if 100 different tickets are purchased ?

How many different ways are there to select 6 items out of 51?

2. anonymous

$\dbinom{51}{6}=18009460$

3. anonymous

this of course assumes that the numbers cannot be repeated.

4. anonymous

that answer is for the one1 person ?

5. anonymous

or is that for the probability of winning with the 100 tickets

6. anonymous

well you only have one of these numbers, so it is $\frac{1}{18009460}$
