We are given table
Month : 1 2 3 4 5
Shoppers: 50 250 1250 6250 3250
so, we have
first term =50
Second term =250
Third term =1250
now, we can find ratios
we can see that all ratios are same and 5
so, this is exponential
so, option-D..........Answer

Answer:
And for this case we want to find this probability:
And we can use the probability mass function and we got:
Step-by-step explanation:
Previous concepts
A Bernoulli trial is "a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted". And this experiment is a particular case of the binomial experiment.
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Solution to the problem
Let X the random variable of interest, on this case we now that:
And for this case we want to find this probability:
And we can use the probability mass function and we got:
