This question as for the earn which is containing two red and two green marbles.
00:16
So this question is in the format of a flow chart.
00:20
So here we have two probabilities for getting red or green.
00:24
So the probabilities will be for getting red is equal to 1 by 2.
00:30
And similarly probability for getting green is also 1 by 2.
00:34
From here we will get our two heads again for getting red and getting green.
00:44
So red will have another two for red and green.
00:53
With the same way we will get calculated here probability of getting all the three hours which is 1 by 2 multiplied by 1 by 2 multiplied by 1 by 2.
01:05
So that is equal to 1 upon 8.
01:08
In the same pattern we will get here red, red and green.
01:14
That will be 1 upon 8 again.
01:17
And similarly, probability of getting red green, red is also 1 by 8.
01:23
Similarly, probability of getting an event for red, green and green, that is 1 upon 8 with the same way...
