@KylaiaJmaa You need to know Binomial probability I think... if you don't know what I'm talking about, best write out all the possible answers and add up all the ones with 2 or 3 heads, and calculate that way. Should be esay considering small numbers.

@frostyKB Yeah, what you said was wrong, as 0.98 is the probability of not happening at a given year, 0,98^50 not happening in 50 years, you are right there, but 1 - P(not happening) is it happening at least once, which is what he was calculating. 0.2 + 0.98^49 would calculate the probability of one, not at least one.

EARTHCAKES. Sounds tasty.

Thank you so much
-
i think the last 2 problems are wrong
Isn't the probability of occurring 1 earthquake in 50 years is
0.02 + 0.98^49? 0.02 is probability of 1 earthquake during some random year,49probability of not happening
If it's 0.98^50 then you are calculating the possibility of no earthq occurring in 50 years
Or maybe i'm horribly wrong and confused

Help me please. How would I find the answer to the question "If you flip a coin 3 times, what is the probability of getting heads at least 2 times?"
-
Oh my god THANK YOU! I've been trying to figure this out for the past 1/2 hour!
-
Why can't my actual statistics professor be this clear? Thank you for the help!

you're automatically cool for being left handed
