One state’s lottery consists of a person choosing 5 different numbers, each between 1-50.
Find the probability of matching all five numbers if…
a) order matters
b) order does not matter
*Please use the P(A)=number of outcomes in event A/total numbers of outcomes formula*
~~~~~~~~~~~~~~~~~

(a) If the order matters, then 

        total numbers of outcomes = 50*49*48*47*46 = 254251200    

            (the product of 5 consecutive integer numbers in descending order, starting from 50);


        number of favorable outcomes = 1.

        The probability is  P = 1%2F254251200.    ANSWER




(b)  If the order does not matter, then

        total numbers of outcomes = C%5B50%5D%5E5 = %2850%2A49%2A48%2A47%2A46%29%2F%281%2A2%2A3%2A4%2A5%29 = 2118760  

            (the number of combinations of 50 items taken 5 at a time);


        number of favorable outcomes = 1.

        The probability is  P = 1%2F2118760.      ANSWER

Solved.
