Suppose major earthquakes in a certain region occur independently of one another at the rateof one every ten years. Find the probability that the next major earthquake will occur between7 and 12 years from now.

Therefore, the probability is P=0.5.

Step-by-step explanation:

We know that a major earthquakes in a certain region occur independently of one another at the rateof one every ten years.

We conclude that:

We calculate the probability that the next major earthquake will occur between7 and 12 years from now. We get:

Therefore, the probability is P=0.5.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
