Probability distributions problem 11


Harry has three coins:


  • One coin is biased so that the probability of obtaining a head when it is thrown is .

  • The second coin is biased so that the probability of obtaining a head when it is thrown is .

  • The third coin is biased so that the probability of obtaining a head when it is thrown is .


Harry throws the three coins. The random variable is the number of heads that he obtains. Draw up the probability distribution table for .
