You are given an unfair coin (the probability of heads is 1/3) and decide to toss it ten times. Following Example 5.3 in your textbook, plot the binomial probability mas function for N = 10 and p = 1/3. What is the probability that the coin will come up heads 5 times in 10 tosses?

Determine the mean, variance, and joint second moments.

Section I You toss a coin and roll a die simultaneously. If the coin shows heads, the experiment outcome is equal to the value shown on the die. If the coin shows tails, the experiment outcome is equal to twice the value shown on the die. Assume that the coin and the die are fair. Let ? be 1 if the coin shows heads and 2 if the coin shows tails, ?be the outcome of rolling the die, and ?...

When coin 1 is flipped, it lands on heads with probability 3 /5 ; when coin 2 is flipped it lands on heads with probability 7 /10 . (a) If coin 1 is flipped 9 times, find the probability that it lands on heads at least 7 times. (b) If one of the coins is randomly selected and flipped 8 times, what is the probability that it lands on heads exactly 5 times? (c) In part (b), given that the...

Coin 1 comes up heads with probability 0.6 and coin 2 with probability 0.5. A coin is continually ﬂipped until it comes up tails, at which time that coin is put aside and we start ﬂipping the other one. (a) What proportion of ﬂips use coin 1? (b) If we start the process with coin 1 what is the probability that coin 2 is used on the ﬁfth ﬂip? (c) What proportion of ﬂips land heads?
