demonstration of slick method to fill a list with probabilities; handy for letting TI calculate mean and SD for a binomial PDF (topic for another video in this playlist)

a simple method to use TI for this calculation

We calculate the probability of exactly 14, exactly 13, and 13 or 14 females in 14 individual births. The syntax for the TI83/84 calculator is
binomcdf(n, p, x)
This video shows that the probability of 13 female births in 14 individual births is quite small. Since 13 is an unusually high number of girls this probability indicates that chance is not a reasonable explanation.
Interpret each of the following graphically. Then, give the syntax for the TI calculator with numerical values replacing parameters.
exactly 7 heads in 15 tosses of a fair coin
at most 7 successes in 15 tosses of a fair coin
at least 7 successes in 15 tosses of a fair coin
Interpret each of the following using a sentence or two.
binompdf(12, 0.5, 11)
binompdf(12, 0.5, 12)
binomcdf(12, 0.5, 11)
binomcdf(12, 0.5, 12)
1-binomcdf(12, 0.5, 10)
