The 1 side and the 2 side of the dice represent the questions he answers correctly. The 3, 4, 5, and 6 sides of the dice represents the questions he answers incorrectly.
Answer:
Box and whisker plots are ideal for comparing distributions because the centre, spread and overall range are immediately apparent
Step-by-step explanation:
It is often used in explanatory data analysis
hope this helped
Answer: False
Step-by-step explanation:
G(x) is not a one-to-one function (since it fails the horizontal line test). Therefore, it doesn't have an inverse.
Answer:
31.77% probability the surgery is successful for exactly five patients.
Step-by-step explanation:
For each patient, there are only two possible outcomes. Either the surgery is successful, or it is not. The probability of the surgery being successful for a patient is independent of other patients. 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.
A surgical technique is performed on seven patients.
This means that 
You are told there is a 70% chance of success.
This means that 
Find the probability the surgery is successful for exactly five patients.
This is P(X = 5).


31.77% probability the surgery is successful for exactly five patients.
