Answer:
The probability is 0.05
Step-by-step explanation:
Since the event of a major earthquake is independent of other major earthquakes, the problem is quite simple. We know that the probability an event like this occurs every ten years is 0.1.
Using this, we can calculate the probability of it happening any one year to be = 0.01
We can multiply this probability by the number of years.
Total number of years: 12 - 7 = 5
Probability the earthquake happens in these 5 years :
= 0.05
Pretty sure it’s b
Because it’s by 2 at first then it’s by 125
I don't want to give you the answer so here is a thorough explanation and an answer if you want it. Set this up as a proportion. Set it up as 5/5=x/12.5. Then multiply 5 by x to get 5x and 12.5 by 5. Once you have this answer, divide it by five to isolate the x. Once you have finished this, you have your answer.
I got the answer 12.5. Make sure you check this so you understand how to solve these kinds of problems.
