... Usually we just write Pr[E] for PrΩ,p [E]. For example consider the probability space {H, T}9 under the uniform distribution modelling sequences of 9 tosses of a random coin. Then the event H1 consisting of those sample points whose first entry is H has probability Pr[H1 ] = 1/2. This can be calcula ...

... (b) What is the probability that it will take at least 5 hours to replace a windshield given that it hasn’t been finished after 2 hours? Solution. There are two ways to do this. The longer one is to calculate P (X > 5|X > 2). The shorter one is to remember that the exponential distribution is memory ...
