The value is 4 because 4b is also 4 times three which is twelve then you divide 12 by three and get 4
No of red marbles = 5
Total number of marbles =14
By using probability formula,
P(E)= Number of favorable outcome /
Total number of outcomes
P(E)= 5/14
I hope that was useful ☻
The answer is 768 (you just multiply by 4)
