The answer is 20 days, we can solve this in following way:
Each friend creates 4 bags of dough and after ten days four bags divided into four more bags means:
3 friends x 4 bags = 12 bags and 12 bags x 4 = 48 bags
so in next 10 days, the 48 bags will be further divided into 4, so
48 x 4 = 192 bags
10 days + next 0 days = 20 days
so 20 days is the answer.
Why’d you put the answer?
Answer:
P = 3/6.
Step-by-step explanation:
there are three odd numbers and three even numbers on a 6-sided die. the probability of rolling an odd number is 50%, which can be converted to 1/2, or 3/6. hope this helps

Answer:
0.173 probability that she gets exactly three questions correct.
Step-by-step explanation:
For each question, there are only two possible outcomes. Either she guesses the correct answer, or she does not. The probability of guessing the correct answer for a question is independent of other questions. 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.
Seven questions:
This means that 
Each question has four choices.
Abby guesses, which means that 
Find the probability to the nearest thousandth, that Abby gets exactly three questions correct.
This is P(X = 3).
