When a group of five single births are recorded what is the probability that at least 4 are boys. Assume that boys and girls are equally likely. (Hint: Need a probability distribution) \n" ); document.write( "---- \n" ); document.write( "Since each birth is either boy or girl this is \n" ); document.write( "a binomial probability problem. \n" ); document.write( "----- \n" ); document.write( "n = 5 ; p = 1/2 \n" ); document.write( "---- \n" ); document.write( "P(x >=4) = 1 - binomcdf(5,0.5,3) = 0.1875 \n" ); document.write( "======================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "========== \n" ); document.write( " |
