With help of permutations and combinations we can calculate the probability of some event to happen,if the event is composed from several other events (when is a list)
If the order of the events doesn't matter then we have a combination, if the order do matter then we have a permutation. We can say that a permutation is an ordered combination.
The number of permutations of n objects taken r at a time is determined by the following formula:P(n,r)=n!(n-r)!
<span>The number of combinations of n objects taken r at a time is determined by the following formula: C(n,r)=n!/(n-r)!r!</span>
Well there is 66 female sheep and 47 male sheep so 66-47=19 so there are 19 more female then male
Answer: I think it is B
Step-by-step explanation: it is definently not A or D because 6 is going to the right. B is prob not it because 7 is being compressed. Take what I say with a grain of salt.
Answer: h = -4
Step-by-step explanation:
-9h-6+12h+40=22
-9h+12h=22+6-40 "collect all unknown values in a side and collect numbers in other side "
"Don't forget to Change signs"
3h= -12
3h/3 = -12/3 "dividing by 3 in both sides"
h= -4
