Total number of times she flipped a coin =200.
Total number of heads in the experiment=92
Total number of tails in the experiment=108
Therefore probability of the coun landing heads up in this experiment is 0.5
In the above experiment, the probability of the coin landing heads up is
P(H)= 92/200 = 0.46
In the above experiment, the probability of the coin landing tails up is P(T) = 108/200 = 0.54
The ratio obj represent the experimental probability of the coin landing heads up in this experiment
Therefore the correct option is 1.
9a^2-6ab+12ac-8bc
=3a(3a-2b)+4c(3a-2b)
=(3a+4c)(3a-2b)
There you go. Have fun!
