We are dealing with experimental probabilities, the reason being that exact quantities of the four types of buttons are not given.
The experimental probability of drawing a cat is 35/100.
The experimental probability of not drawing a cat is given by:
$$P(other\ than \ a\ cat)=1-\frac{35}{100}=you\ can\ calculate$$
When you have the result, multiply it by 100 to convert it to a percentage.

$$P(other\ than\ a\ cat)=1-\frac{35}{100}=0.65$$
$$0.65\times100=65\ percent$$
The correct choice is B: 65%
