Hello!
The answer for A is:
The answer for B is: The rocket will hit the lake surface in 5 seconds.
<h2>Why?</h2>Defining the terms:
So, replacing it in the quadratic equation (it's given to you in the exercise)\\
We are working with a quadratic equation, so we will have two possible results,
Now, we are asked to find the time, time can not be a negative value, we have to discard X1 (-1) since it's a negative value, knowing that, the rocket will hit the lake after 5 seconds.
Have a nice day!
Answer:
2.99% probability that the cost will be paid by only one team
Step-by-step explanation:
The binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Probability that a team plays:
A team plays if it has at most 2 injured players out of 11.
11 players, so
Each player with a 5% probability of injury, so
Then
In which
Each team has a 0.9848 probability of showing up to play.
What is the probability that the cost will be paid by only one team?
This happens if one team shows up and the other do not.
2 teams, so
Each team has a 0.9848 probability of showing up to play, so .
This probability is P(X = 1).
2.99% probability that the cost will be paid by only one team
