A binomial distribution models the [ ] in a fixed number of trials.
A
No - success is only a label for the counted outcome.
B
A binomial distribution models the number of successes in a fixed number of trials.
C
P(14.5<Y<25.5)P(14.5<Y<25.5)P(14.5<Y<25.5)
D
P(X=r)=(nr)pr(1−p)n−rP(X=r)=\binom{n}{r}p^r(1-p)^{n-r}P(X=r)=(rn)pr(1−p)n−r
