Probability in 2000 of picking a Turkey out of a group composed only of Turkeys and Hogs is
(#of Turkeys in 2000)/(#of Turkeys and Hogs in 2000)
In 2000 ratio of Sheeps/Turkey= 1/4
Turkey= 4*Sheeps = 4*0.04*56028
Hogs= .03*56028
Therefore
(#of Turkeys in 2000)/(#of Turkeys and Hogs in 2000)=
(4*0.04*56028)/(4*0.04*56028 + .03*56028) =
.16/.19 =
16/19
Final Answer: C
(#of Turkeys in 2000)/(#of Turkeys and Hogs in 2000)
In 2000 ratio of Sheeps/Turkey= 1/4
Turkey= 4*Sheeps = 4*0.04*56028
Hogs= .03*56028
Therefore
(#of Turkeys in 2000)/(#of Turkeys and Hogs in 2000)=
(4*0.04*56028)/(4*0.04*56028 + .03*56028) =
.16/.19 =
16/19
Final Answer: C
