Hi!
Let's find out how much he has to pay for each of the deals.
Deal 1
£1.75 per mile.
192 x 1.75 = 336
£336
Deal 2
15% off of £680
680 x 15 = 10200
10200/100 = 102
680 - 102 = 578
£578
Deal 3
£90 per day - 1/10
90 x 7 = 630
1/10 of 630 = 63
630 - 63 = 567
£567
The cheapest deal would be Deal 1
Hope this helps! :)

Answer:
a) There is a 1.21% probability that both contain diet soda.
b) There is a 79.21% probability that both contain diet soda.
c) is unusual,
is not unusual
d) There is a 19.58% probability that exactly one is diet and exactly one is regular.
Step-by-step explanation:
There are only two possible outcomes. Either the can has diet soda, or it hasn't. So we use the binomial probability distribution.
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 combinatios of x objects from a set of n elements, given by the following formula.
And is the probability of X happening.
A number of sucesses is considered unusually low if
and unusually high if
In this problem, we have that:
Two cans are randomly chosen, so
Two out of 18 cans are filled with diet coke, so
a) Determine the probability that both contain diet soda. P(both diet soda)
That is P(X = 2).
There is a 1.21% probability that both contain diet soda.
b)Determine the probability that both contain regular soda. P(both regular)
That is P(X = 0).
There is a 79.21% probability that both contain diet soda.
c) Would this be unusual?
We have that is unusual, since
For P(X = 0), it is not unusually high nor unusually low.
d) Determine the probability that exactly one is diet and exactly one is regular. P(one diet and one regular)
That is P(X = 1).
There is a 19.58% probability that exactly one is diet and exactly one is regular.
Firstly they are not numbers, they are ordered pairs or points with a form yes they probably lie on a function graph but that would be rather impossible to find out. The function may be linear, exponential, logarithmic etc. we can't tell. All we can tell is that if these ordered pairs
lie on a function graph
where
where D is definition set of function defined x's and T a transformation set of f(x)'s for this function. So yes they may lie on some lambda function but they themselves are nothing but an ordered pairs with no meaningful connection.
Hope this helps.
