Answer:

Step-by-step explanation:
Let the names of 4 players start with letters A, B, C and D.
There is the the only chance that they shoot free throws in alphabetical order (ABCD).
Count how many different ways are to choose 4 letters from the hat. First letter can be chosen in 4 ways, the second letter can be chosen in 3 ways (only 3 letters left), the third letter can be chosen in 2 ways (only 2 letters left) and the fourth letter can be chosen in 1 way (the last letter left). So, there are

different orders.
The probability is

By making all three roots to be square roots of 3. And then add them.
Answer:
The second beach has a higher chance of being dry.
Step-by-step explanation:
At the first beach, it rained 5 out of 30 days. 5 over 30 is 1/6. 10% which is the second beach's rain rate is equivalent to 1/10. since 1/6 is greater than 1/10, the second beach will have a lower rain rate.
