Hi everyone, my question is if you have three coins and you flip them all together at the same time for a hundred times, how many times will they come up evens (all heads or all tails) and what percentage will be heads and what percentage will be tails.

P (H & H & H) = P(H) * P(H) * P(H) = A
P (T & T & T) = P(T) * P(T) * P(T) = B

P(A or B) = P(A) + P(B) = Z

Z * 100 = times it will be even
A * 100 = times it will be heads
B * 100 = times it will be tails

QI says that the chance of it being heads is 1% more

P (T & T & T) = P(T) * P(T) * P(T) = B

P(A or B) = P(A) + P(B) = Z

Z * 100 = times it will be even
A * 100 = times it will be heads
B * 100 = times it will be tails


That looks like my old Stats assignment... but we had to chart it out too
