So if a pair of dye is rolled, that is the random experiment.
00:04
A pair of die is rolled.
00:06
That means that is the random experiment.
00:09
In first die, six faces or six sides.
00:13
In second die also, six faces or six sides.
00:17
So the number of sample points or sample spaces have this combination.
00:21
1 -1, similarly 1 -2, like that up to 1 -6.
00:27
Then similarly for 2 1 2 will come on the first die and 1 will come on the second die similarly 2 2 up to 2 6.
00:38
Similarly we will 3 4 5 and last 1 6 1 6 2 up to 6 6 6 so these are the number of possible cases or points the sample space is actually the sample space when 2 die are told so out of the sample space, we have to, we are more concerned about the sum of five, when five will occur.
01:04
We have clearly seen that five will occur for three, two, three, four, four one, four one, and remaining four cases.
01:19
These are the only cases where sum of five will occur...
