Solution

Solution Steps

Step 1: Understanding the Problem

We are given the percentages of Americans with different blood types. We need to find the probability that a randomly chosen American has type A blood.

Step 2: Identifying the Given Information

The percentage of Americans with type A blood is given as 42%.

Step 3: Calculating the Probability

The probability that a randomly chosen American has type A blood is equal to the percentage of Americans with type A blood, expressed as a probability. Since probabilities are expressed as decimals, we convert the percentage to a decimal by dividing by 100.

\[ P(\text{Type A}) = \frac{42}{100} = 0.42 \]
