Solution:

(i) In the form of conditional statement, expression is

If $p$, then $q$

So now,

In the statement $p$ and $q$ are

$p$: You do not study

$q$: you will fail.

As a result, if you don’t study, then you will fail.”

Solution:

(ii) In the form of conditional statement, expression is

If $p$, then $q$

So now,

In the statement $p$ and $q$ are

$p$: An integer is divisible by 5

$q$: Unit digits of an integer are 0 or 5

As a result, if an integer is divisible by 5, then its unit digits are 0 or 5.
