Hi, i'm david and i'm here to help you answer your question.
00:03
Now let me bring up your question here in the question here we are going to discuss about the table of probability from the two events now let me formally the table here for the two events a and b so we have the event b1 so this will be the total.
00:37
This is an answer the total.
00:39
And we have 4 .a, we have the 0 .14, 0 .10, 015, and the 0 .09.
00:49
This isn't get equal to the 0 .15, 0 .17, 010, and the 0 .10.
00:57
So the total, here we get the 0 .29, the 0 .27.
01:03
7, 0 .25 and the 0 .19.
01:07
And here we have 0 .14 plus 1 plus 0 .15 plus 0 .09 equal to the 0148 and this will be the 0152.
01:22
And that will be the summary of the table.
01:25
Now in the question a, asking us to find the probability of the event a occur.
01:31
So we'll be just equal to the 0 .48.
01:33
48 and then for the question b, want to find the probability that p2 occurs.
01:42
So b2 will be the 0 .27.
01:45
For the question c, want to find the probability that the a2 and b4 occur.
01:53
So probability a complement and the b4.
01:58
So it will be a common moment and the b4...
