Theprobability(P) of getting a question right if you guess: .25 The number of questions on the test (n)*: 20 P x n = .25 x 20 = 5 *You might see this as X instead. This type of expected value is called anexpected value for a binomialrandom variable.It’s abinomial experiment...

To find the probability of 0, 1, or 2 heads, we can either use binomial probability, or note that there are 4 equally likely outcomes in the sample space: {HH, HT, T H, T T }. The results are shown in the following table, which gives the probability distribution for the number...
We propose a parallelization method that transforms the calculation of the expected value into an embarrassingly parallel problem by mapping the branches of the binomial tree to the processes in a multiprocessor computing environment. We also discuss a parallel Monte Carlo method and verify the ...

Expected Value and the Lottery As another example, consider a lottery. Although millions can be won for the price of a $1 ticket, the expected value of a lottery game shows how unfairly it is constructed. Suppose for $1 you choose six numbers from 1 to 48. The probability of choosing ...
