A company advertises two car tire models. The number of thousands of miles that the standard model tires last has a mean \mu_S =

60μ S ​ =60 and standard deviation \sigma_S = 5σ S ​ =5. The number of miles that the extended life tires last has a mean \mu_E = 70μ E ​ =70 and standard deviation \sigma_E = 7σ E ​ =7. If mileages for both tires follow a normal distribution, what is the probability that a randomly selected standard model tire will get more mileage than a randomly selected extended life tire?

Answer:

29

Step-by-step explanation:

Use definition of conditional probability:

P(A|B)=\dfrac{P(A\cap B)}{P(B)},

where

A = the student is a freshman,

B = the student is a male

From the table,

P(B)=\dfrac{4+6+2+2}{4+6+2+2+3+4+6+3}=\dfrac{14}{30}=\dfrac{7}{15}\\ \\P(A\cap B)=\dfrac{4}{4+6+2+2+3+4+6+3}=\dfrac{4}{30}=\dfrac{2}{15}

So,

P(A|B)=\dfrac{\frac{2}{15}}{\frac{7}{15}}=\dfrac{2}{7}\approx 0.29=29\%

An 8-sided die is rolled. Find the probability of rolling a 1 or even number
leonid [27]

The probability of rolling a 1 or an even number is 5/8.

If there are 8 sides of the die from numbers 1-8, the numbers of the probability are 1, 2, 4, 6, and 8. That makes 5 numbers out of 8 possible numbers. So, the probability is 5/8.(62.5%)
