Acappuccino vending machine is designed to dispense an average of μ oz per cup. if the ounces per fill are normally distributed, with a standard deviation of 0.4 oz, at what value should μ be set so that 66 oz cups will overflow only 22 % of the time?
a.6.82 oz
b.6.00 oz
c.5.18 oz
d.5.60 oz

Iwas going to ask that quesytion  sorry dude i dont  know : (    : /

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
