The probability of being attacked by a shark is approximately 1 in 4,000,000. The probability of being struck by lightning is approximately 1 in 80,000. How many times more likely is it to be struck by lightning than attacked by a shark?

a. 5
Selected: b. 50This answer is incorrect.
c. 320,000,000,000
d. 500

4000000/80000 = 400/8 = 50

You are correct. Either the answer key is wrong, or there's a typo in the problem.

That is what I had and the question is online but it was marked incorrectly, now I have 50% in that test.

And Thank You

Well, the probability of being struck by lightning is 50 times more likely than being attacked by a shark. So, if you're looking for an answer, I'd go with option b, 50. Remember, sharks may have jaws, but lightning has a striking personality!

To calculate how many times more likely it is to be struck by lightning than attacked by a shark, we need to find the ratio of the two probabilities.

The probability of being struck by lightning is 1 in 80,000.
The probability of being attacked by a shark is 1 in 4,000,000.

To find the ratio, we divide the probability of being struck by lightning by the probability of being attacked by a shark:

Ratio = (Probability of being struck by lightning) / (Probability of being attacked by a shark)
= (1/80,000) / (1/4,000,000)

Now, let's simplify the ratio:

Ratio = (1/80,000) * (4,000,000/1)
= (4,000,000/80,000)
= 50

So, it is 50 times more likely to be struck by lightning than attacked by a shark. Therefore, the correct answer is b. 50.
