P(X ≤ 3).

This is the probability that there will be 3 or fewer births.This is the probability that there will be fewer than 3 births.     This is the probability that there will be 3 births.This is the probability that there will be more than 3 births.This is the probability that there will be 3 or more births.

1 − P(X ≤ 3).

This is the probability that there will be 3 or fewer births.This is the probability that there will be fewer than 3 births.     This is the probability that there will be 3 births.This is the probability that there will be more than 3 births.This is the probability that there will be 3 or more births.
