Answer:
0.213 is the required probability.
Step-by-step explanation:
We are given the following information:
We treat person booking from online travel website as a success.
P(Booking through online travel website) = 0.68
Then the number of people follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 15
P(exactly ten people out of fifteen people used an online travel website)
0.213 is the probability that exactly ten people out of fifteen people used an online travel website when they booked their hotel.
Answer:
0.24
Step-by-step explanation:
From the information given:
Let's have a schematic view of a tree diagram
A
P(Santa Cruz) P(Isabella)
= 13/15 = 2/15
P(Success | Santa Cruz) = 0.09 P(Success | Isabella) = x
We are told that many have tried to locate the giant turtle, but 89% of them have failed.
This means the probability of success is:
P(success) = 1 - 0.89 = 0.11
We need to find P(Success | Isabella),
Suppose P(Success | Isabella) be x as shown above,
Then:
P (Success) = P(Santa) P((Success | Santa Cruz) + P(Isabella) P(Success | Isabella)
make x the subject of the formula:
x = 0.032/0.133
x = 0.24
