Question

Elena randomly chooses a number from 1 to 10. What is the probability she chooses a number greater than 5?

Answer 1

1/2

Explanation:

Ape x

Answer 2

`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)`
