What is the probability that a randomly selected person prefers sausage or vegetables as their favorite pizza topping?
A. 45%
B. 60%
C. 45/100
D. 55/100
To calculate the probability that a randomly selected person prefers sausage or vegetables as their favorite pizza topping, we need to add the percentages of those who prefer sausage and vegetables.
Let's start by finding the percentage of people who prefer sausage: 15%.
Next, let's find the percentage of people who prefer vegetables: 30%.
To find the probability of choosing either sausage or vegetables, we add these percentages together: 15% + 30% = 45%.
Therefore, the probability that a randomly selected person prefers sausage or vegetables as their favorite pizza topping is 45%.
So, the correct answer is A. 45%.
