Answer:
A. What happens on one trial affects the probability on the next: they are dependent events.
Step-by-step explanation:
Below are some important characteristic of a binomial experiment:-
- A binomial experiment has n trials.
- Each trials has two possible outcomes. Success or failure.
- The probability of success is same in very trail.
- The event is independent event. In other words, the probability of one event doesn't effect the other.
- The coefficient of the binomial term can be determined using Pascal’s triangle
Basis these characteristics, only the first option is not a properties of a binomial experiment. In case of binomial experiment, the event is independent event.
Hence, option A is correct.
(3c+s)(100-20)/100=100 multiply both sides by 100
(3c+s)80=10000 divide both sides by 80
3c+s=125 subtract 3c from both sides...
s=125-3c....now let's look at the second situation...
(4c+2s)(100-40)/100=120 multiply both sides by 100
60(4c+2s)=12000 divide both sides by 60
4c+2s=200 divide both sides 2
2c+s=100 subtract 2c from both sides
s=100-2c, and from earlier we saw that s=125-3c, since s=s:
100-2c=125-3c add 3c to both sides
100+c=125 subtract 100 from both sides
c=25, and since s=100-2c
s=50
So cds cost $25.00 and sweatshirts cost $50.00
Is there supposed to be a picture in a little bit confused, or are u wanting the definition?
