The total number of tosses is 12 + 6 = 18.
The experimental probability of getting heads is the number of times we got heads divided by the total number of tosses:
P(heads) = number of heads / total number of tosses
= 12 / 18
= 2 / 3
Therefore, the probability of getting heads is 2/3 or 0.6667 as a decimal.
Similarly, the experimental probability of getting tails is:
P(tails) = number of tails / total number of tosses
= 6 / 18
= 1 / 3
Therefore, the probability of getting tails is 1/3 or 0.3333 as a decimal.
