Answer:
The answer to this is the 3rd choice which is 1a) 4/12, 1b) 3/12, 1c) 12/144.
Step-by-step explanation:
This is pretty simple. To identify the probability of the yellow marbles, you can find the amount of yellow marbles and the total amount of marbles. You take it as a fraction which would be 4/12.
The total amount of marbles : 3 purple + 5 green + 4 yellow = 12 total marbles
The amount of yellow marbles : 4 yellow
Probability of yellow marbles : 4/12
To identify the probability of the yellow marbles, you can find the amount of purple marbles and the total amount of marbles. You take it as a fraction which would be 3/12.
The total amount of marbles : 3 purple + 5 green + 4 yellow = 12 total marbles
The amount of purple marbles : 3 purple
Probability of purple marbles : 3/12
To identify the probability of both the yellow and purple marbles, you can find the amount of yellow and purple marbles along with the total amount of marbles. Since we know this from the work above, you just need to multiply both probabilities. You take it as a fraction which would be 12/144.
The total amount of marbles : 3 purple + 5 green + 4 yellow = 12 total marbles
The amount of yellow marbles : 4 yellow
The amount of purple marbles : 3 purple
Probability of yellow marbles : 4/12
Probability of purple marbles : 3/12
Probability of both marbles : 12/144
