a basket ball player makes 75 percent of his free throw attempts.
1- what is the probability that he makes 10 out of 12 attempts?
2- what is the probability that he makes at least 10 of 12 attempts?
3- what is the expected number of successes in 12 trails?
this is binary ... make or not make
1- 66 m^10 n^2 ... 66 * .75^10 * .25^2
2- 10, 11, or 12 ... (66 m^10 n^2) + (12 m^11 n) + m^12
3- 75% of 12 ... .75 * 12 = ?
