Asurvey of 100 households that own televisions found that 95 use a remote control. if you randomly knocked on two doors (from the sample of 100 households), what is the probability that the first homeowner would use a remote control and the second homeowner would not?

Probability of first using a remote = 95/100
Probability of second not using a remote = 5/99

Overall prob = (95/100)(5/99)

 95*5/100*99 =475/9900 =19/396

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
