Binomial distribution conditond
Two outcomes success and fail
Fixed probability of succes and fail
Trials are independent of one another
How to do
You are finding now many ways you can choose your combinations fo success and fails in a tree thus
n choose r x success to the power of r x failure to the power of 1-r
Expectation of binomial si
Nx p
How to find the most probable outcome of x and why do you know for anfsct thisnidnthis
In binomial disruptions there is only ONE PEAK with symmetry on both sides
Thus if you enter values close to the mean and seee they start to fall then that’s the higher definition
Mean for binomial probability ?
= prob x number of trails
ALWAYS REARSNGE THE EXPONENETIALS using the bracket forumula to get rid of e and ln
How to find out how many roots
B2-4ac always
