a bag with 10 marbles has 2 blue marbles and 8 yellow marbles. a marble is chosen from the bag at random. what is the probability that it is red? write your answer as a fraction in simplest form.

Answer

Explanation:

Step1: Find number of red marbles

The bag has 10 marbles in total, 2 blue and 8 yellow. So the number of red marbles is $10-(2 + 8)=0$.

Step2: Calculate probability

The probability formula is $P(\text{event})=\frac{\text{number of favorable outcomes}}{\text{total number of outcomes}}$. Here, the number of favorable outcomes (red marbles) is 0 and total number of outcomes is 10. So the probability $P(\text{red})=\frac{0}{10}=0$.

Answer:

$0$
