Question
Transcribed Image Text:If you toss four coins together at the
same time, what's the probability of
getting all "heads"? You may
remember that you can use the
multiplication rule to get 1/2 x 1/2 x 1/2
x 1/2 1/16. However, most people
can't quickly figure out the probability
of getting three "heads" and one
"tails." Can you? You could use the
approach of considering each coin 1,
2, 3, and 4, as we learned in Lab
Module 1. However, figuring out how
many ways you can get three "heads"
and one "tails" isn't trivial, and it
becomes even harder as you move to
five, six, seven, or more coins.
