Fifty-five percent of the applications received for a particular credit card are accepted. among the next twelve applications, what is the probability that all will be rejected?

0.00007

Step-by-step explanation:

The binomial distribution formula :-

P(X)=^nC_xp^x(1-p)^{n-x}, P(X) is the probability of getting success in x trials , n is total n umber of trials and p is the probbaility of getting success in each trial.

Given : The probability that the applications received for a particular credit card are accepted = 0.55

The number of applications : n= 12

Then , the probability that all will be rejected (i.e. none of them will be accepted):-

Hence, the probability that all will be rejected = 0.00007

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
