ANSWER
![P(E)=\frac{1}{2}](https://tex.z-dn.net/?f=P%28E%29%3D%5Cfrac%7B1%7D%7B2%7D%20)
EXPLANATION
From the given information, Elena chooses a number from 1 to 10.
The sample space is
S={1,2,3,4,5,6,7,8,9,10}
n(S)=10
The numbers greater than 5 are:
E={6,7,8,9,10}
n(E)=5
The probability that, she chooses a number greater than 5 is:
![P(E) = \frac{n(E)}{n(S)}](https://tex.z-dn.net/?f=P%28E%29%20%3D%20%20%5Cfrac%7Bn%28E%29%7D%7Bn%28S%29%7D%20)
Substitute the values,
![P(E) = \frac{5}{10}](https://tex.z-dn.net/?f=P%28E%29%20%3D%20%20%5Cfrac%7B5%7D%7B10%7D%20)
![P(E) = \frac{1}{2}](https://tex.z-dn.net/?f=P%28E%29%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Answer:
