Alice and Bob have 9 coins, each with probability of a head equal to p = .6. Bob tosses 5 coins, while Alice tosses the remaining 4 coins. Assuming that all tosses are independent, compute the probability that Bob gets more heads than Alice.

Answer #1

Note :: The probability is calculated using the R-software by the codes:

p=function(x) dbinom(x,5,0.6)
q=function(x) dbinom(x,4,0.6)
prob=0
for(i in 2:5){
{for(j in 1:(i-1))
prob=prob+p(i)*q(j)}}
prob

We have two coins whose heads are marked 2 and tails marked 1. One is a fair coin and the other is a biased coin whose probabilities of 'Head' are 1/2 and 1/4 respectively.Suppose we toss the two coins simultaneously. Let S and P be the sum and product of all the outcome numbers on the coins, respectively. 1. Compute the mean and variance of S. Calculate up to 3 decimal places (round the number at 4th place) if necessary....

Each day, starting at 5pm, Alice starts to wait for Bob’s call. It is known that each day, the waiting time for Bob’s call is an Exponential random variable with expectation 1/2 hour, and that the times of his calls are independent from day to day. Alice’s day is unhappy if she has to wait for more than log 10 hours for Bob’s call. (As log 10 hours is about 2.3 hours, Alice is not being unreasonable.) (a) Compute the...
