Will give brainliest! which of the following events has a probability of 1? check all that apply. landing on a blue or red space on a spinner with 1 blue space and 1 red space choosing a red marble from a bag containing red and green marbles drawing a peanut from a bag of trail mix with 4 types of nuts drawing a red card from a stack of 20 red cards getting a heads or a tails when flipping a coin. check all that apply!

Alright, so I'm not too good with probability, but I have a general idea for what the answers may be. But, please do fact check this before submitting it as I cannot guarantee the accuracy.

As for the answer, I think that these are the right answers:

(1) Landing on a blue or red space on a spinner with 1 blue space and 1 red space.

(4) Drawing a red card from a stack of 20 red cards.

(5) Getting a heads or a tails when flipping a coin.

I find these to be the answers because there's no variation within them. You'll always land on red or blue if the options on the spinner are only red and blue. You'll always pull a red card from a stack of red cards. And you'll always get heads or tails when flipping a coin. The others are incorrect because there's a possibility you won't get the given selection. So the conclusion would be that those 3 ^ are right because a probability of 1 means that you're guaranteed to get a certain outcome.
