Answer:
The expectation and variance for the number of 1s in the sequence of die rolls is: 1/6
If the coin was unfair the change is: 1/2
The probability of obtainig heads was: 51%
Step-by-step explanation:
In probability and statistics theory:
The expectation and variance possibilities gotten rolling one dice are six.
In independent Bernoulli trials sequence with probability 1/2 of success on each trial is metaphorically called a fair coin.
By the other hand if the probability is not 1/2, it is called a biased or unfair coin.
It might be thought that the toss of a coin is always a 50/50 probability, with a 50 percent chance it lands on heads, and a 50 percent chance it lands on tails but if it starts out as heads, there's a 51% chance that it will end as heads.
