A small model airplane motor has 4 starting components: key, battery, wire, and glow plug. What is the probability that the system will work if the probability that each component will work as follows: key (0.998), battery (0.997), wire (0.999), and plug (0.995)?

as they are independant, i.e. they do not affect each other's probability eg rolling a die and flipping a coin, we simply multiply the probabilties.
0.998*0.997*0.999*0.995=0.98904093903

Simply multiply the probabilities together to get a probability they ALL happen,
So 0.998 x 0.997 x 0.999 x 0.995 which is 0.98904093903

There s a model airplane with four component parts.The probability of each component working: key: 0.988; battery: 0.979; wire: 0.977 (except using two wires in parallel); plug: 0.970 What is the probability of that this system of serial components will work?

mutliply the 4 probes with eachother is the prob that the airplane will work. it is not a reliable plane.

....Wild guess. 4 start ups in 100 wont work.
Tell me if I'm right
I'd be supprised.
I suck at math.

I don't know...
I'm guessing that it will work 98% of the time...

there is a 98.9 chance it will work all u have to do is multiply them :)

Probably none if you put it together.
