What is the probability of exactly three heads in four flips of a coin given at least two are heads?
If you know that two of the four are already heads, then all you need to find is the probability of exactly one heads in the last two flips. Number of possible outcomes of one flip of one coin = 2 Number of possible outcomes in two flips = 4 Number of the four outcomes that include a single heads = 2. Probability of a single heads in the last two flips = 2/4 =…
Slightly loosen or tighten the bolts that are pulling down the head. If you have a fairly cheap set of bongos this may not be possible. If the bongos don't have tuning pegs (bolts) and the heads are synthetic (plastic or mylar or something) then you are out of luck. If the heads are natural - goatskin or calfskin or something like that then you can loosen by added humidity or moisture to the head…
