Please help me with 3 and 4

Third choice, likely

Second choice, equally likely

Step-by-step explanation:

There's 14 red ones and 3 green ones, so there's 17 marbles in total. !4 red ones so the probability is 14/17, which is a very high chance so yea

It's not certain because there's still 3 marbles that are not red, so while the chance of it not being red is low, it's not none so u can't choose certain

There's only 2 sides to a coin, so the chance of getting either heads or tails is 1/2. So there's an equal chance

they aren't great and cause destruction, idk man
