Everyone let us look into the machine.
00:04
Here the number and frequency are given.
00:09
So the frequent numbers we can consider it as 2, 3, 4, 5, 6, 7, 8, 9, 10.
00:17
And the frequencies are 3, 8, 21, 20, 17, 22, 45, 20, 13, 7.
00:28
The total is 186.
00:31
Hence we can have n equal to 186.
00:35
And event a represents the number selected by the student is 6.
00:45
And b represents an event that the student selected an odd number.
00:50
Student selected an odd number.
00:59
Like 1, 3, 5, 7, 9.
01:03
Then p of a.
01:05
P of a represents the probability of a student selected a number 6.
01:10
So it is 22 divided by 186.
01:14
So it is 0 .1183.
01:17
Next one is probability of p which means that probability of a student selected odd number...
