Answer 1

We know that the probability of an event or other is additive, so we will have that the probability that sneakers or boots will be the favorite shoe of the next reader is:

`P(sneakers\text{ }or\text{ }boots)=54+16\Rightarrow P(sneakers\text{ }or\text{ }boots)=70`

So, the probability is 70%.
