Answer:
The percentage of the price of television reduced to <u>20%</u>.
Step-by-step explanation:
Given:
The price of a television was reduced $250 to $200.
Now, to find the percentage of the reduced price of television.
So, to get the reduced amount of television:
Old price = $250.
New price = $200.
Reduced amount = $250 - $200 = $50.
Now, to get the percentage of price reduced:




Therefore, the percentage of the price of television reduced to 20%.
This is a binomial experiment and you'll use the binomial probability distribution because:
- There are two choices for each birth. Either you get a girl or you get a boy. So there are two outcomes to each trial. This is where the "bi" comes from in "binomial" (bi means 2).
- Each birth is independent of any other birth. The probability of getting a girl is the same for each trial. In this case, the probability is p = 1/2 = 0.5 = 50%
- There are fixed number of trials. In this case, there are 5 births so n = 5 is the number of trials.
Since all of those conditions above are met, this means we have a binomial experiment.
Some textbooks may split up item #2 into two parts, but I chose to place them together since they are similar ideas.
