the answer will be close to 50% so maybe like 48% or 49%
Step-by-step explanation:
The reasoning behind this is that the are 11 marbles total and half of 11 is 5 and a half. There are 5 red marbles which means that the chances are close 50% but because 5 isn't exactly half of 11 this means that your answer will need to be close to 50% but not exactly 50% which is why i gave the choices 49% or 48%.
