The probability of only one person out of three selected use their phones while driving is 0.147875.
How to find the probability at least two of them use their cell phone while driving?
Probability is a way of evaluating how likely something is to happen. Many things are difficult to forecast with absolute certainty.The branch of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
[tex]probability = \frac{the \: numbers \: of \: favourable \: outcomes }{total \: number \: of \: possible \: outcomes} [/tex]
given that
According to an online poll, 35% of American motorists routinely use their cell phones while driving.
so, the percentage of motorists who use their phone while driving is 35%.
The total percentage of motorists who use or don not use their phone while driving is 100%.
now ,find the the percentage of motorists who don't use their phone while driving.
the percentage of motorists who don't use their phone while driving = 100% - 35% = 65% .
So, the probability of using phone while driving p(using phone) = 35/100 = 0.35.
the probability of not using phone while driving p(not using phone) = 65/100 = 0.65.
The probability of only one person out of three seted use their phones while driving is
(0.35)(0.65) (0.65) = 0.147875.
Hence,the probability of only one person out of three selected use their phones while driving is 0.147875.
