For each time up at bat, a baseball player has a 70% chance of making an out, a 10% chance of getting walked, and a 20% chance of getting a hit. Estimate the probability that , out of 5 at-bats, the player gets at least one hit.

A) About 30%
B) About 70%
C) 100%
D) About 20%
E) About 90%

Any help is greatly appreciated and thanks in advance!

Ummmm...it says he has a 20% chance of getting a hit. Out of 5 at bats, 1 hit would be 20%. So what is the probability that he will get a hit 20% of the time? 100%. It is stated in the question.

but what if he was walked the 5 at bats then his probability wouldn't be 100%. I know it seems obvious but I am overthinking this and I can't see how it would be 100%. We see baseball players go with streaks like 15 times without hitting the ball.

its still 20%. well now i cant decide between 20 and 70

damn, i feel like this problem is so easy but i second guess my answer every time i tell myself it has to be 20%
however, i am 100% positive the answer isnt 100%

Really?
#1 20% per at bat multiplied by 5 at bats means he will likeley get a hit. Subtract the 70% K rate you get back to 30%. Of course a walk is as good as a K in this scenario so subtract that 50% you get -20. Add 50 to get 30%

Ok, I'm only going to say this once. The likelihood of him getting a hit doesn't increase the more at bats he has.
Using the heads/tails analogy, would I be more likely to get a tails after 10 consecutive heads? NO!
Therefore, the answer is 20%.
