1. ## Binominal probability, one task only: )

A type of seed has 80% chance to bloom. You plant 250 seeds.
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 $\Pr(X \geq 210)$.

This can be easily found using technology.

Alternatively, the normal approximation can be used (why?).
