Which of the following propositional formulae represents the sentence, 'He will come in the $8:15$ or the $9:15$ train; if the former, he will have time to visit us', where

•  $p$ means 'He will come in the $8:15$ train'
• $q$ means 'He will come in the $9:15$ train'
• $r$ means 'He will have time to visit us'
1. $p \rightarrow q \vee r$
2. $p \vee q \rightarrow r$
3. $( p \rightarrow q) \wedge ( p \vee r )$
4. $(p \vee q ) \wedge (p \rightarrow r)$

Former - previous one or earlier one. Here the first sentence

But previous sentence is 'q' not 'p'.

It should be (p+q)(q--->r).

Is it wrong?
