Answer:
Invalid/ valid depending on the explanation.
Step-by-step explanation:
This is because using the Law of Syllogism,
P If you<u> see a leopard</u> then <u>you will want to run.</u>
Q If you <u>want to run</u>, then you <u>will try to run</u>.
R If <u>you run the leopard will chase you. </u>
There is no then and would result in a cause with no effect. Since there is no effect, then Mr.Small wont save you.
However, even if you put aside the way it is written, you can say that it is still invalid due to the law of Syllogism. P --> Q and Q--> R
Each event would lead to another but this phrase
Mr. Small won't save you if the leopard is not chasing you
This doesn't mean that Mr.Small will save you if the leopard chases you.
Unless it says If the leopard is chasing you, then Mr.Small will save you, it won't be valid.
