Hello everyone.
00:01
So in this question it is given that a sample of 75 people viewed the following information about their health insurance, which are 70, out of the 75, 33, managed car plan, managed car plan, 27 traditional insurance, insurance, while 15 had no insurance.
00:52
Right now two people were provided two people who provided the information for the table was selected random without replacement we have to determine the probability that neither had traditional insurance insurance so if 27 had traditional insurance then remaining 48 out of 75 were having no traditional insurance.
01:27
So out of these 48, two can be selected in 48 c2 ways, full divided by 75c2, 75c2, which is equal to 0 .4539.
01:42
Let us come to part b.
01:45
In part b, we have to tell the probability that both managed car plan.
02:03
There were 33 who managed car plan.
02:04
There were 33 who managed car plan.
02:06
So out of these 33, we can select 2 in 33 c2 ways, multiplied by the total 27.
02:12
75.
02:12
So 75c2.
02:14
This is equal to 0 .2125.
02:18
So these are 67 and 68.
02:24
67, 68...
