A coin was flipped four times. Let T be the number of tails that come out.
A. Construct the probability distribution of the random variable
B.Construct the probability histogram
A.
There are "2^4=16" possible outcomes
"HHTT, HTHT, HTTH, THTH, THHT, TTHH,"
"HTTT, THTT, TTHT, TTTH, TTTT\\}"
The possible values of the random variable "T" are "0, 1, 2, 3, 4."
We will assume that the probability of getting heads and tails is the same:
Construct the probability distribution of the random variable
or
B.Construct the probability histogram
