A drawer contains 3 blue ribbons, 4 red ribbons, and 3 green ribbons. A ribbon is randomly chosen from the drawer, replaced, and another ribbon is chosen. Find each probability"
Blue = 3/10
Red = 4/10 = 2/5
Green = 3/10
7/10
To find the probability of choosing a certain color ribbon, we need to divide the number of ribbons of that color by the total number of ribbons.
1. Probability of choosing a blue ribbon:
There are 3 blue ribbons in the drawer, and the total number of ribbons is 3 + 4 + 3 = 10.
So, the probability of choosing a blue ribbon is 3/10.
2. Probability of choosing a red ribbon:
There are 4 red ribbons in the drawer, and the total number of ribbons is 10.
So, the probability of choosing a red ribbon is 4/10, which can be simplified to 2/5.
3. Probability of choosing a green ribbon:
There are 3 green ribbons in the drawer, and the total number of ribbons is 10.
So, the probability of choosing a green ribbon is 3/10.
It is important to note that when a ribbon is chosen and replaced, the total number of ribbons remains the same for each subsequent choice.
