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

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

answer: 20
