Suppose that the probability that a person books a hotel using an online travel website is 0.68. For the questions that follow,
1 answer:
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.

Given:
f(x) = 2x² + 3
g(x) = x² - 7
To Find:
(f - g)(x)
Step-by-step explanation:
(f -g)(x) = f(x) - g(x)
= (2x² + 3) - (x² - 7)
= 2x² + 3 - x² + 7
= 2x² - x² + 3 + 7
= x² + 3 + 7
= x² + 10
