A company selling light bulbs claims in its ads that their average life is 1000 hours. In fact, the life span of these light bulbs is normally distributed with a mean of 1000 hours and a standard deviation of 100 hours. What is the probability that a randomly chosen light bulb will last between 1000 and 1100 hours?

if this was to u plzz mark me the brainliest

no one knows lol

step-by-step explanation:

i think the correct option is the second option.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
