Window – adjacent (0.33) – Not adjacent (0.667)
Aisle – adjacent (0.667) – Not adjacent (0.33
P(y/x) what is probability that y occurs on condition that x is occurring
- P(window + adjacent) = P(wind) + P(adj/win) = ½ x 1/3 = 1/6
Flip a coin 3 time. What is probability of getting at least one head.
P(HHH) = ½ x ½ x ½ = 1/8
-all of probability add up to 1. So we calculature probability by 1 – probability of
what we don’t want.
- we define compliment and then do 1 – probability of what we don’t want
Rare Event Rule
-under some assumption we think something is true about a population. So then we
go get samples.
-what is probability NEW TOPIC: LECTURE 5 NOTES
Random Variable: something that can take on different value but we don’t know
