here as events are independent and probability of head or tail on a flip =1.2
hence b) probability of HHHT =(1/2)*(1/2)*(1/2)*(1/2) =1/16
c)P(getting all heads or no heds)=P(HHHH)+P(TTTT)=(1/16)+(1/16)=1/8
b. What is the chance of getting this particular sequence: HHHT? Submit Answer Incorrect. Tries 2/3...

heads in 72 tosses. 1.4 +/- 2 heads in 8 tosses is about as likely as 36 +/- a. Step 1: Compare n, the number of tosses in the two cases. 72 is t imes more than 8? Submit Answer Incorrect. Tries 1/4 Previous Tries b. Step 2: Since we are counting (summing), the error will be multiplied by how much? Submit Answer Tries 0/4 heads in 72 tosses. c.

3. (PMF – 8 points) Consider a sequence of independent trials of fair coin tossing. Let X denote a random variable that indicates the number of coin tosses you tried until you get heads for the first time and let y denote a random variable that indicates the number of coin tosses you tried until you get tails for the first time. For example, X = 1 and Y = 2 if you get heads on the first try and...
