So in the given question, it's we have been provided the number of customers in nine at a supermarket at texas checkout counter.
00:09
It's represented by random variable, which is x.
00:13
And the probability distribution of x is given to us.
00:17
So the first part of the question is to determine the probability at 2.
00:22
So this we can directly answer from by looking at the table that at 2, the first part of the problem.
00:30
Probability is 0 .30.
00:33
So we turn to the first part is 0 .30.
00:36
Now the next part is to determine the probability of no more than 1.
00:46
So no more than 1 is equal to, this is equal to 1 minus probability of x is equal to 0.
00:55
First probability of x is equal to 1, right? so this will be equal to 1 minus at 0 the probability is point 1 of 0 .01 plus okay so it will be 0 .0 to the point to 5 this will be 0 .01 plus 0 .25 so this will be 0 .01 plus 0 .25 so this will be 0 .74 so this is the problem.
01:51
Of no more than one next is to determine the probability that no one is in line so it means the problem of the probability distribution we observe that the probability that corresponds to the this corresponds to the probability of zero this is equal to 0 .10 right this is the answer to the third part next we have been to determine the probability that at least three people are in line...
