Okay, so here we are given that the weather condition of today depends on the previous two days.
00:06
So it's known that if it has rained for the past two days, then it will rain today with the probability of 0 .7.
00:13
And if it did not rain for any of the past two days, then it will rain today with a probability with a probability of 0 .4.
00:22
And in any other case, the weather today will, with a probability of 50 % or 0 .5, be the same as the weather yesterday.
00:33
Okay.
00:34
So here we can say that in this probably state zero as if it rained today and yesterday, state one, if it rained today and not yesterday.
00:42
State two, if it rained yesterday and not today.
00:45
And state three, if it did not rain either yesterday or today.
00:51
So if we then let the event that it rained be denoted by r and not rained as nr, with the probability of rrr is 0 .7...
