In a photocopy center, there are two small photocopiers, two medium
photocopiers and one big photocopier. The probability
that a small one fails and requires repairs is 0.1, a medium
one fails and requires repairs is 0.08, and the probability
that the big photocopier fails and requires repairs is 0.05.
Assume that all five copiers operate independently.
a. What is the probability that all the photocopiers fail
and require repairs?
b. What is the probability that none of the photocopiers
fails and requires repairs?
c. What is the probability that one of the photocopiers
fails and requires repairs?
d. What is the probability that one of the small photo-
copiers fails and requires repairs?
e. What is the probability that at least one of the five
copiers fails and requires repairs?

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.

c. side angle side. u shares the same sides

the answer is mp

step-by-step explanation:

b is the correct answer
