Answer
$P(at~least~2)=0.358$
If we randomly select 25 visitors to the ER 1000 times, we would expect about 358 trials result in at least 2 of 25 will die within 1 year.
Work Step by Step
The probability that at least 2 of 25 visitors will die is the complement of the probability that fewer than 2 of 25 visitors will die.
Using the Complement Rule (see page 275):
$P(at~least~2)=P(X\geq2)=1-P(X\lt2)=1-0.642=0.358$
