Question

Please help me solve this

Answer 1

B

Explanation:

A rational number can be expressed in the form

`(a)/(b)` ← where a and b are integers

From the set

3 is rational as it can be expressed as
`(3)/(1)`

and
`√(9)` = 3 ← rational

`√(2)`,
`√(3)` and
`√(7)` ← are irrational numbers

Thus there are 2 rational numbers out of the 5 given, thus

P( rational ) =
`(2)/(5)` → B
