Whats the probability for at least 210 to bloom? sorry for english, not mother tongue Let X be the random variable number of seeds that bloom. X ~ Binomial(n = 250, p = 0.8) Calculate $\displaystyle \Pr(X \geq 210)$. This can be easily found using technology. Alternatively, the normal approximation can be used (why?).
Thanks alot: )
