if one customer shows up, and she buys one song, that's $1.29, if she doesn't buy anymore, then that's the charge.

the first song is always at a full price, and after that, to encourage buying, the next ones are just 99 cents, let's see how it goes after a few songs purchases.

1 song.........................$1.29

2 songs.......................$1.29 + 0.99(2)

3 songs.......................$1.29 + 0.99(3)

4 songs.......................$1.29 + 0.99(4)

c songs.......................$1.29 + 0.99(c)

s(c) = 1.29 + 0.99c.

natta225 [31]

Answer:

The probability that there will be repair exactly 3 toaster is 0.0574.

Step-by-step explanation:

Binomial Distribution:

A discrete random variable X having the set {0,1,2,3......,n} as the spectrum, is said have a binomial distribution with parameter n= number of trials and p=probability of number of success on an individual trial, if the p.m.f (probability mass function) of X given by,

P(X=x)=C(n,x)p^x(1-p)^{n-x}    x=0,1,2,......,n

               =0                                   elsewhere

where 0<p<1 and n is a positive integer.

Total number of toaster in cartons(n) = 10.

Probability of number of success on an individual trial p= 10% = 0.10

\therefore P(X=3)= C(10,3)(0.10)^3(1-0.10)^{10-3}

                    =\frac{10!}{3!(10-3)!}(0.10)^3)(0.90)^7

                    =0.0574

The probability that there will be repair exactly 3 toaster is 0.0574.
