Two people enter the elevator in a 5-floor building. let and denote the floors that they want to go to. assume that and are independent and equtl to 2, 3, 4 and 5 with probabilities 1/4 ) write down the joint pmf

a. is correct

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
