Four coins are tossed.Let T be the random variable representing the number of tails that occur.find the values of the random variable T
This is a binomial distribution with "n=4,p=\\frac{1}{2}."
"P(T=0)=C_4^0(\\frac{1}{2})^0(\\frac{1}{2})^4=\\frac{1}{16}."
"P(T=1)=C_4^1(\\frac{1}{2})^1(\\frac{1}{2})^3=\\frac{1}{4}."
"P(T=2)=C_4^2(\\frac{1}{2})^2(\\frac{1}{2})^2=\\frac{3}{8}."
"P(T=3)=C_4^3(\\frac{1}{2})^0(\\frac{1}{2})^1=\\frac{1}{4}."
"P(T=4)=C_4^4(\\frac{1}{2})^0(\\frac{1}{2})^0=\\frac{1}{16}."
