Answer:
b. 3.775
Step-by-step explanation:
The question is worded incorrectly since the sum of the first 100 counting numbers is actually greater than the sum of the first 50 counting numbers.
The sum of any set of consecutive numbers of size 'n' is given by:
Where A1 is the first number on the set and An is the last number.
The sum of the first 100 counting numbers (1 through 100) is:
The sum of the first 50 counting numbers (1 through 50) is:
The difference between those two values is:
Therefore, the sum of the first 100 counting numbers is 3,775 greater than the sum of the first 50 counting numbers.

Answer:
C
Step-by-step explanation:
If we know that the event will <em>definitely</em> happen, then there is no doubt and no probability that the event will <em>not</em> happen.
This means that the probability is 1, which is the same as 100%.
It raining in Alaska and raining in Ohio are independent events. One does not control the other or affect the other in any way.
For two independent events (let's call them A and B), the Probability of A and B both occurring is given by P(A and B) = P(B) x P(B).
For this problem, let A = rain in Ohio and B= rain in Alaska.
P(A and B) = P(A) x P(B)
