Answer:
14.29% probability that Marlon's friend will think of the number 9
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
There are 7 numbers from 5 to 11(5,6,7,8,9,10,11)
9 is one of them
So
14.29% probability that Marlon's friend will think of the number 9
Answer:
35.03% probability that fewer than 7 will be carrying backpacks
Step-by-step explanation:
For each student, there are only two possible outcomes. Either they are carrying a backpack, or they are not. The probability of a student carrying a backpack is independent from other students. So we use the binomial probability distribution 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.
The probability that an Oxnard University student is carrying a backpack is .70.
This means that
If 10 students are observed at random, what is the probability that fewer than 7 will be carrying backpacks
This is when
. So
35.03% probability that fewer than 7 will be carrying backpacks
Answer:
<u><em>He made a loss of 6.67%</em></u>
Step-by-step explanation:
Loss percentage =
Loss = 50
Cost price = 750
Hence, Loss percentage=
= = 6.66 %
He made a loss of 6.6666%.
This amount can be rounded up to 6.67%
