If four tires are randomly selected for installation on a car, what is the probablity that they are all good?The wheeling tire company produced 5000 tires that includes 200 that are defective.
The probability of getting a defective tyre `= 200/5000`
Therefore the probability of getting a good tyre `= 1-0.04`
Therefore the probability of all four tyres can be good
`= 0.96 xx 0.96 xx 0.96 xx 0.96`
Therefore, there is 0.8493 chance of all four tyres are good.
