The human resources managet at a company records the length in hours of one shift at work, X. He created the probability distribution below. What is the probability that a worker chosen at random works at least 8 hours?​

The probability that a worker chosen at random works at least 8 hours is 0.83

Step-by-step explanation:

Given

See attachment for probability distribution

Required

At least 8 hours means that a worker works for 8 hours or more.

So:

By reading the probabilities from the graph, we have:

step-by-step explanation:

when the line is solid:

it's either < or >

when the line is dashed:

it's either < or >

this > inequality sign means:

greater thanmore thanaboveexceeds

this < inequality sign means:

less thanfewer thanbelow

this > inequality sign means:

greater than/equal tono less thanat leastminimum of

this < inequality sign means:

less than/equal tono more thanat mostmaximum of

about the problem:

since the line is solid, that means it's either < or >

srry i'm not done ! i'll

The answer would be $68.04
