x = 12
Step-by-step explanation:
x - 5 = 84/x
x² - 5x = 84
x² - 5x - 84 = 0
x = (5 ±√(5² - 4(1)(-84))) / 2
x = (5 ± 19) / 2
x = -7 ignore
x = 12
Answer:
4 / 20 (1 / 5)
20%
Step-by-step explanation:
The experimental probability is what actually happens in an experiment (as opposed to an authentic probability calculated from genetics).
In this experiment, there are 3 outcomes with :
3 tails and 1 head
(tails represent female, head represent male)
So, 4 / 20 of the time, this coin flip was what we call a "success" (meaning that it matches the guidelines that we want)
4 / 20 = 20% of the time
So, the probability of a group of 4 puppies being 3 females and 1 male is :
4 / 20 (1 / 5)
20%
