Ellen flipped a coin 80 times. the coin landed heads up 44 times and tails up 36 times. what is the experimental probability of landing tails up

Step-by-step explanation:

experimental probability is the probability of an event occuring when we perform an experiment.

It goes according to the results of the experiment, not the theory behind it.

Probability of landing tails up, therefore, is the number of times it came tails up divided by the total number of times the coin was flipped.

Hence

P (tails) = 36/80 = 9/20

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
