So I'm confused if whether I should do the multiplication rule after calculating the probability for each individual from the US and UK that don't have blood type O (this is #2 from problem 2).

Problem #2 All people have a certain "blood type". THose types can be one of four possibilities: Type A, Type B, Type AB, or Type O. Shown below are the percentage of these various blood types among people in the United States: Blood Type: O P(Blood Type in US) 0.43 0.03 0.46 Also shown is a similar table, but this one giving the breakdown of blood types in the United Kingdom: Blood Type: T AB O P(Blood Type in the U.K.) 0.37 0.04 0.49 For the problems that follow, assume that the blood-type of an American and the blood-type of someone in the UK are independent of one another. 1. Suppose we randomly choose a single individual at random from the US and another individual from the UK. calculate the probability that both of those people will be of blood-type A. 2. Now let's repeat this: Select one American and another from the UK. This time, determine the probability that neither of them is of blood type O. 3. Suppose that we randomly select 3 people from the US. Determine the probability that none of them are of blood-type B
