Question 847145: Use the characteristics of a binomial experiment.
Seventeen percent of married couples say they are planning a trip to Europe. You randomly select 15 married couples and ask each if they are planning to travel to Europe.
1. What is the probability that exactly 1 couple says they plan to travel to Europe?
2. What is the probability that more than 1 couple say they plan to travel to Europe?
3. What is the probability that at most 2 couples say they plan to travel to Europe?
4. What is the probability that less than 5 couples say they plan to travel to Europe?

Use the characteristics of a binomial experiment.
Seventeen percent of married couples say they are planning a trip to Europe. You randomly select 15 married couples and ask each if they are planning to travel to Europe.
X~Binomial(15, 0.17)
1. What is the probability that exactly 1 couple says they plan to travel to Europe?
P(X = 1) = =

2. What is the probability that more than 1 couple say they plan to travel to Europe?
P(X > 1) = 1 - P(X ≤ 1)
=
=
3. What is the probability that at most 2 couples say they plan to travel to Europe?
P(X ≤ 2) =
=
4. What is the probability that less than 5 couples say they plan to travel to Europe?
P(X < 5) =
=
