Its main purpose is to improve organizational practices, eliminate silos, keep employees informed and reduce errors. Effective business communication is essential for success and growth of every organization. Unlike everyday communications, business communication is always goal oriented.Jul 9, 2020A coin is biased so that the head is 3 times as likely to occur as tail. If the coin is tossed twice, find the probability distribution of number of tails.

Answer

Let the probability of getting a tail in the biased coin be x.

∴P(T)=x

⇒P(H)=3x

For a biased coin, P(T)+P(H)=1

⇒x+3x=1

⇒4x=1

⇒x=41

∴P(T)=41 and P(H)=43

When the coin is tossed twice, the sample space is {HH,TT,HT,TH}.

Let X be the random variable representing the number of tails.

∴P(X=0)=P(notail)=P(H)×P(H)=43×43=169

P(X=1)=P(onetail)=P(HT)+P(TH)

=43⋅41+41⋅
