The number of marbles in each jar are this.
00:05
Now, to calculate the probability of each jar.
00:15
First, in jar 1, the probability of red marbles are 600 upon 600 plus is 0 .6.
00:34
6.
00:36
The probability of white marble is 400 upon 600 plus 400.
00:46
That is 0 .4.
00:49
Then in jar 2, probability of red marble is probability of blue marble is 900 100 plus 100 is 0 .9 and probability of white marble is 100 upon 900 plus 100 is 0 .1.
01:25
In jard 3, the probability of green marble is 10 plus 990 equal to 0 .01 and probability of white marble is 990 upon 990 plus 10 is 0 .99 .9.
01:54
So the probability of selecting red marble, a blue marble and a green marble can be calculated as p red, multiple blue, multiplied by p green is 0 .6 multiplied by 0 .6.
02:21
0 .9 multiplied by 0 .01 is 0 .054.
02:29
The probability of selecting a red marble from the first jar, a green marble from the third jar, and a white marble from the second jar is p red, again p green, and p white is equal to 0 .6, 0 .5 .5.
02:54
0 .1 and 0 .1.
02:57
It is 0 .006.
03:00
And the probability of selecting a red marble from the first jar, a white marble from both the second jar and is third jar is probability of red, probability of green and probability of white is equal to 0 .6, 0 .99, 0 .1 is equal to 0 .0 .0 .0 .0 .1 is equal to 0 .0 .0 .0 .0 .0 .0 .1 .1 .1.
03:29
1 is equal to 0.
