ANSWER

P(E)=(1)/(2)

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) = (n(E))/(n(S))

Substitute the values,

P(E) = (5)/(10)

P(E) = (1)/(2)
