Twenty-five percent of the customers entering a grocery store between 5 P. M. and 7 P. M. use an express checkout. Consider five randomly selected customers, and let x denote the number among the five who use the express checkout. Find the probability that 2 of the customers use the express checkout.

The required probability = 0.2637

Step-by-step explanation:

Let X represents the no of customers that uses the express checkout.

The probability mass function is given by:

To find:

P(X = 2) = 0.2637

Thus, the required probability = 0.2637

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
