80% of a gram.
One gram is $100, aka $100 is 100% of a gram, so $80 would be 80% of a gram.

sergeinik [125]
The answer is 28.
Check: 28-12= 16
1/4 of 16= 4

so Carmen takes 3/4 more time of the trip to the market when she return s home.

Answer:

There is a 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.

Step-by-step explanation:

For each question, there are only two possible outcomes. Either it is correct, or it is not. This means that we use the binomial probability distribution to solve this problem.

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 p is the probability of X happening.

In this problem we have that:

There are four questions, so n = 4.

Each question has 5 options, one of which is correct. So  

What is the probability that he answers exactly 1 question correctly in the last 4 questions?

This is  

There is a 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.
