a coin is flipped 10 times. the coin is a fair coin so each outcome is equally likely. what is the probability that the number of flips that come up heads is not equal to 4.

20 percentage, you can also do it on a calculator.

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
