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

Lorico [155]

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

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

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)

$P(x = 10)\\\\= \binom{15}{10}(0.68)^{10}(1-0.68)^5 \\\\= 0.213$

0.213 is the probability that exactly ten people out of fifteen people used an online travel website when they booked their hotel.

Tamara is planting bushes around her house. So far today she has planted 5 bushes and she wants to plant at least 12 bushes toda

bixtya [17]

Answer:

$b+5\geq 12$

Step-by-step explanation:

Given:

Number of bushes planted = 5

Minimum number of bushes to be planted = 12

Let the number of bushes planted after planting 5 bushes be $b$ .

Since, Tamara has already planted 5 bushes, total number of bushes planted is given as:

$b+5$

Now, as per question, total number of bushes should be 12 or greater than 12.

Therefore, $b+5\geq 12$ .
