Hello there! The answer is A, 1/2.
Basically, there are ten numbers from 1 to 10. Five, or 1/2, of these numbers are greater than five (6, 7, 8, 9 and 10) and the other five (1, 2, 3, 4, 5) are less than or equal to five.
I hope this was helpful, have a great rest of your day!
The probability she chooses a number greater than 5 is 1/2.
What is Probability?
- The extent to which an event is likely to occur.
- It is measured by the ratio of the favorable cases to the whole number of cases possible.
- The value of the probability of an event happening can lie between 0 and 1 because the favorable number of outcomes can never cross the total number of outcomes.
Elena randomly chooses a number from 1 to 10.
The sample space exists
S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
n(S) = 10
The numbers greater than 5 exists:
E = {6, 7, 8, 9, 10}
n(E) = 5
The probability that, she selects a number greater than 5 exists:
[tex]$P(E)=\frac{n(E)}{n(S)}$[/tex]
Substitute the values,
P(E) = 5/10
P(E) = 1/2
Therefore, the correct answer is option C. 1/2.
