Consider a binomial distribution with 15 identical trials, and a probability of success of 0.5 \r
\n" ); document.write( "\n" ); document.write( "i. Find the probability that x = 2 using the binomial tables
\n" ); document.write( "P(x=2) = 15C2(1/2)^2(1/2)^13 = 105(1/2)^15 = 105/2^15 = 0.0032043....

\n" ); document.write( "\n" ); document.write( "ii. Use the normal approximation to find the probability that x = 2.
\n" ); document.write( "Ans: P(x=2) = 0
\n" ); document.write( "Comment: The probability of any particular number is zero because the
