For this question, this is a probable question, but there are some choices, and we have to select the right choice here.
00:07
And so they are given some information here.
00:11
So let me just define the random variable here.
00:14
Let's x denotes the number of repair this one here.
00:19
So it is given that, so in one year period, 17 % of the cars will need to be repaired only once.
00:27
So when x is equal to 1, this is 17%, which is 0 .17.
00:32
And so twice which is 0 .4 so this is x is equal to 2 the probability is 0 .04 4 x is equal to 2 the probability should be 7 % and when it is 3 or more so the axis is greater than 3 or more which is equal to 4 % this is 0 .04 so we have to use if you want to use the multiplication rule first of all for the multiplication rule i'm just right here 4 this is 4 part a for multiplication rule.
01:06
Multiplication rule.
01:08
So the events should be independent.
01:17
So we have to look at the choice, which includes something about the independent...
