Question 383966
The probability for a defective resistor is,
{{{P(D)=3/12=0.25}}}
The probability for a non-defective resistor is,
{{{P(ND)=0.75}}}
.
.
.
Find the probabilities for defective resistors from {{{0}}} to {{{4}}} out of 4 total.
{{{P(0)=1*(0.75)^(4)*(0.25)^(0)=0.3164}}}
{{{P(1)=4*(0.75)^(3)*(0.25)^(1)=0.4219}}}
{{{P(2)=6*(0.75)^(2)*(0.25)^(2)=0.2109}}}
{{{P(3)=4*(0.75)^(1)*(0.25)^(3)=0.0469}}}
{{{P(4)=1*(0.75)^(0)*(0.25)^(4)=0.0039}}}

a){{{P(0)=0.3164}}}
b){{{P(1)=0.4219}}}
c){{{P(3)=0.0469}}}
