Answer:
The probability that all will last at least 30,000 miles is 0.3164.
Step-by-step explanation:
Consider the provided information.
For a particular tire brand, the probability of wearing out before 30,000 miles is 0.25. Someone who buys a set of four of these tires,
That means the probability of not wearing out is 1-0.25 = 0.75
Now use the binomial distribution formula.

Substitute p = 0.25, q=0.75, r=4 and n=4



The probability that all will last at least 30,000 miles is 0.3164.
Answer:
Positive co terminal angle = -105°
Negative co terminal angle = 225°
Step-by-step explanation:
We have been given the angle 75° and we have to find one positive and one negative co-terminal angle.
In order to find the co terminal angle, we add and subtract 180° to the given angle.
Therefore, the negative co terminal angle is given by
75 - 180 = -105°
And the positive co terminal angle is given by
75 + 180 = 225°
