Percentages in Probability

[watsonworms]

This is an issue I ran into during the activity Probability models. (Though when I got an error using the Khan's site issue submission, it told me to reference L'hopital's Rule.)

2 things:

1. The problem assumed (but never asked for) rounding to the nearest hundreth (0.35) and did not accept the true value of 353/1000 of 0.353.
2. Less of an issue, but a percentage (35%) was not accepted, despite 35% being offered as a possible solution in the final hint. (The problem only accepted 0.35 as the answer.)
