Step-by-step explanation:

This is already in simplest form. it can't be reduced furthermore.
As a mixed number is 5 1/4
As a decimal is 5.25
Answer:
The probability is 5/36
Step-by-step explanation:
The total number of marbles is 2 + 4 + 1 + 5 = 12 marbles
The probability of randomly drawing a green marble would be
number of green marble/total number of marbles = 4/12 = 1/3
Now since we are replacing the total number of marbles stays the same
so, the probability of drawing a yellow marble now will be ;
number of yellow marbles/total number of marbles = 5/12
So the total probability we are having here would be; 1/3 * 5/12 = 5/36
