because 40% of $98 is $39.20
The dictionary price before the reduction is $44
From the question, we have the following parameters that can be used in our computation:
Reduction = 30%
Price after = $30.80
Using the above as a guide, we have the following:
Price after = Price before * (1 - Reduction)
substitute the known values in the above equation, so, we have the following representation
Price before * (1 - 30%) = 30.80
Evaluate
Price before = 44
Hence, the dictionary price before the reduction is $44

Answer:
Well the original price would be $44
Step-by-step explanation:
So make an equation
Lets make X stand for the price before the deduction
so x-x(0.3)=30.80
Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change
Now just solve the equation
You’ll get 44.

In the second version, you are given five attempts, but the target is smaller, and you estimate that your probability of
success on any given throw is 0.05. The prizes for the two versions of the game are the same, and you are willing to
assume that the outcomes of your throws are independent. Which version of the game should you choose? (Hint: In
the first version of the game, the probability that you do not get the prize is the probability that you fail on all three
attempts.)
Answer:
And the probability of loss with the first wersion is 0.729
And the probability of loss with the first wersion is 0.774
As we can see the best alternative is the first version since the probability of loss is lower than the probability of loss on version 2.
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Alternative 1
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We can find the probability of loss like this P(X=0) and if we find this probability we got this:
And the probability of loss with the first wersion is 0.729
Alternative 2
Let Y the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We can find the probability of loss like this P(Y=0) and if we find this probability we got this:
And the probability of loss with the first wersion is 0.774
As we can see the best alternative is the first version since the probability of loss is lower than the probability of loss on version 2.

Inductive reasoning is supply of strong evidence with out proof
I will only answer the first one.
Try figuring the second one out yourself
Hope I helped :)
