If I flip a coin 20 times, I get a sequence of Heads (H) and tails (T).] i. How many different sequences of heads and tails are possible?
ii. How many different sequences have at most 2 heads?
iii. How many different sequences have at least three heads?

You from US?

if yes then thank me

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
