You flip a FAIR coin 4 times and count the number of times your coin lands on heads. Calculate and graph the random variable's probability distribution.

This does not make sense

The amount used= 13.04- 1.9 = 11.14

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
