The number of customers in a line at a supermarket express checkout counter is a random variable with the following probability distribution. x 0 1 2 3 4 5 P(x) 0.09 0.26 0.29 0.20 0.09 0.07 Find P(2 or fewer).

probability (x ≤2) = 0.64

Step-by-step explanation:

P(2 or fewer) = probability of 2 or fewer

probability of (2 or fewer) = probability (x ≤2)

probability of (2 or fewer) = probability when x is 0 + probability when x is 1 + probability when x is 2

probability of (2 or fewer) = probability (x =0) + probability of (x =1 ) + probability (x= 2)

probability of (x=0) = 0.09

probability of (x=1) = 0.26

probability of (x =2) = 0.29

probability of (2 or fewer) = 0.09 + 0.26 + 0.29 = 0.64

probability (2 or fewer) = probability (x ≤2) = 0.64

And replacing we got:

And the probability that X would be 2 or lower is 0.64

Step-by-step explanation:

For this case we have the following probability distribution:

x         0       1       2       3         4      5

P(x) 0.09 0.26  0.29  0.20  0.09  0.07

And we want to find the following probability:

And we can find the probability like this:

And replacing we got:

And the probability that X would be 2 or lower is 0.64
