QUESTION:
A die is thrown twice what is the probability that will mat came up
either time
(a) 5 will come up atleast once?
ANSWER :
A DIE IS THROWN TWICE
Sample space =
{(1,1),(1,2),(1,3),(1,4),(1,5),(1,6)
(2,1),(2,2),(2,3),(2,4),(2,5),(2,6)
(3,1),(3,2),(3,3),(3,4),(3,5),(3,6)
(4,1),(4,2),(4,3),(4,4),(4,5),(4,6)
(5,1),(5,2),(5,3),(5,4),(5,5),(5,6)
(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)}
N(s) =36
Let be the event E 'getting a 5 will come up atleast once'
Sample space ={ (5,1),(5,2),(5,3),(5,4),(5,5),(5,6), (1,5),(2,5),(3,5),(4,5),(6,5)}
n(E) = 11
P(E) =n(E)/n(s)
=11/36
