The number of pumps in use at both a six-pump station and a four-pump station will be determined. Give the possible values for a.? ?T = the total number of pumps in use b.?? = the difference between the numbers in use at stations 1 and 2 c.?? = the maximum? ?number of pumps in use at either station d.?? = the number of stations having exactly two pumps in use

Answer : Step 1 : Given the number of pumps in use at both a six-pump station and a four-pump station will be determined. a). Now we have to give the possible values for T. Here T = total number of pumps in use at both stations. We know that The number of pumps in use at both a six-pump station and a four-pump station. So possible values : 0, 1, 2, 3, 4, 5, 6, 7,8, 9, 10. Step 2 : b). Here X = the difference between the numbers in use at stations 1 and 2. So X = -4,-3,-2,-1,0,1,2,3,4,5,6
