How are you thinking about solving this problem?
honestly, I have no clue...
Have you heard about the Binomial Distribution? https://en.wikipedia.org/wiki/Binomial_distribution You will need this
Okay, I think I got this now... kinda
Ok. Tell me.
Just tell me in a sentence, don't worry about the math
Sentences in math, oi... its actually easy for write out the equation instead...Not quite sure about this but here is what I got (250/20)*(0.07)^20*(0.93^231)=0.846 Am I right or wrong?
You've got the flavor of it. We need to count all the ways of having more than 20 people out of 250. This is hard. Let's do something easier, let's count the number of ways to have LESS than 20 people. That's easier. That's our strategy.l In a sentence (or two).
Once we have the probability of less or equal 20, we will subtract this from 1 to get the probability of greater than 20.
Okay, let me try working something else out real quick
I checked with my teacher and she helped me work the problem but thanks for the help, you got me started so i could finish.
