Use common sense to determine whether the given event is impossible; possible, but very unlikely; or possible and likely. an accountant was struck by lightening three times in his lifetime. possible and likely possible, but very unlikely impossible

Option B is the right answer.

Step-by-step explanation:

An accountant was struck by lightening three times in his lifetime. This event is Possible, but very unlikely.

We know that a probability near 0 means an unlikely event. Probability around 1/2 indicates an event that is neither unlikely nor likely. Similarly, probability near 1 indicates a likely event.

Here, in a lifetime the accountant was struck 3 times. If the average lifetime is 70 years, so probability becomes . This is close to zero, indicating that the event is very unlikely.

And people are struck by lightening so it is a possible event.

Combining both, we get option B as the final answer.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
