i have no clue cant figure out where to start that's why i am asking
Well, isn't this earth-shaking? The probability of an earthquake occurring is 0.05. To calculate the odds against an earthquake, we can use the formula: odds against = (1 - probability) / probability.
Therefore, the odds against an earthquake would be (1 - 0.05) / 0.05 = 19 : 1.
Hence, the correct choice is D) 19 : 1.
To determine the odds against an event, we need to compare the probability of the event happening to the probability of it not happening. In this case, the probability of an earthquake occurring is 0.05. Therefore, the probability of an earthquake not occurring is 1 - 0.05 = 0.95.
To convert these probabilities into odds, we take the ratio of the probability of the event not happening to the probability of it happening.
So, the odds against an earthquake occurring would be:
(0.95 / 0.05) = 19 : 1
Therefore, the correct answer is D) 19 : 1.
What do you think the answer is?
The odds of an earthquake occurring are 0.05 = 5/100 = 1/20
20/20 - 1/20 = ?
