There are many event, in real life, which have binary outcomes (A or B0 which are equally likely. In studying such situations the coin probabilities are obvious analogies.
The probability of 2 coins both landing on heads or both landing on tails is 1/2 because there are 4 possible outcomes. Head, head. Head, tails. Tails, tails. Tails, heads. Tails, heads is different from heads, tails for reasons I am unsure of.
The probability of a fair coin landing on heads or tails is even, i.e. 50/50.
It is 1/2.
There is no difference in sound landing heads or tails.
The probability of the coin flip being heads or tails is 100%.
Since it is a certainty that a coin must land on either heads or tails, the probability must be 1.
What is the chance of it landing on heads twice in a row?
They are 0.5 each.
It is 1/2.
The probability of 2 coins both landing on heads or both landing on tails is 1/2 because there are 4 possible outcomes. Head, head. Head, tails. Tails, tails. Tails, heads. Tails, heads is different from heads, tails for reasons I am unsure of.
The probability of a fair coin landing on heads or tails is even, i.e. 50/50.
The experimental probability of a coin landing on heads is 7/ 12. if the coin landed on tails 30 timefind the number of tosses?
Experimental probability is calculated by taking the data produced from a performed experiment and calculating probability from that data. An example would be flipping a coin. The theoretical probability of landing on heads is 50%, .5 or 1/2, as is the theoretical probability of landing on tails. If during an experiment, however, a coin is flipped 100 times and lands on heads 60 times and tails 40 times, the experimental probability for this experiment for landing on heads is 60%, .6 or 6/10. The experimental probability of landing on tails would be 40%, .4, or 6/10.
It is 1/2.
The side heads is slightly heavier giving it a greater likely hood of landing on tails.
There is no difference in sound landing heads or tails.
The probability is 0%. The result will be heads or it will be tails but it cannot be heads and tails.
