    so there are 3 keys that start it, and 7 that don't. which means 3/10 start the car. Now what is 3/10?

    So 30% would be the probability of the first pull

    she then returns the key to the bag, and tries again, But the key that she picks, does not start the car, Which means another 70%, since she returned her last key.

    All of this is so confusing!!! How would i write the answer? They say 'what is the probability of this no start, no start outcome'.

    They are asking for the probability of them both having the same outcome. you would just write the answer as (answer)%. I Understand, as this is a bit confusing to me also, I'm only in eighth grade!

    so, I may be wrong, I just want you to know this.So i would try to check this answer in any way you could. Or maybe ask your teacher/instructor. I got .51 or 51% in the answer form.
