"Binomial probability of a binomial experniment having 'n' trial with probability of success 'p' and probability of failure 'q.' probability that there will be exactly 'r' seccess." to understand all this was hard not even the formula (P(r)=nCr pr qn-r). i didn't understand what my teacher said to me and i didn't undersantd my notes. it was hard to do my homework. so i remember what my someone told me. i went to the enternet and went to a website http://www.khanacademy.com/ and wrote binomial probability and like magic i found it and i got it.
'r' is equal the number of times the tril is successful and 'n' equals the number of titrials. so the probability times 'r' equals the 'n' combination 'r' and probability with an exponent of 'r' and q offailur to the 'n' mines 'r.'
easy i got it and i could solve a word equation.
