a bag with 12 marbles has 12 blue marbles. a marble is chosen from the bag at random. what is the probability that it is blue? write your answer as a fraction in simplest form.
Answer
Answer:
1
Explanation:
Step1: Recall probability formula
$P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$
Step2: Identify favorable and total outcomes
Number of favorable outcomes (blue marbles) = 12, Total number of outcomes = 12
Step3: Calculate probability
$P=\frac{12}{12}=1$
