When grapes are drawn, with replacement, from a mixed bag of seeded and seedless grapes, X is the number of seedless grapes in 3 draws.

When grapes are drawn, without replacement, from a mixed bag of seeded and seedless grapes, X is the number of seedless grapes in 3 draws.

When grapes are drawn, without replacement, from a mixed bag of seeded and seedless grapes, X is the number of times it takes to get a seedless grape.

Answer 1

I think the answer is A, because B and C are incorrect and D doesn't make much sense to me ..
@Dude ??

Answer 2

Yes

I'll also add that you want replacement, otherwise it wouldn't be a binomial probability. You also want to have a number of trials because we are looking for probability.

Requirements:
• Needs *independent* trials (specific number)
• 2 outcomes
• No modifications are made to the outcome

Answer 3

B)
