Answer:
Distribution is NOT binomial.
Step-by-step explanation:
In order to be a binomial distribution, the probability of success for each individual trial must be the same. Since each marksman hits the target with probability Pi, the probability of success (hitting the target) is not necessarily equal for all trials. Therefore, the distribution is not binomial.
In this case, the distribution would only be binomial if Pi was the same for every "ith" marksman.
Answer:
16,383.33 years ( approx )
Step-by-step explanation:
Given equation that shows the amount of carbon-14 after t years,
Where,
= initial amount,
∵ 14% of = 
= 
Taking ln both sides,
Hence, the painting would be 16383.33 years old ( approx )
X= is the number looked for.
56% of x=14
We suggest this equation:
(56/100)x=14
x=(14*100)/56=25
Solution: 25
