Abox contains four balls one red ball, one blue ball, and two green balls. we repeatedly draw a random ball from the box with replacement until we have chosen at least oneball of each of three colors. find e(y), wherey is the number of draws.

1/32

Step-by-step explanation:

First find the probability of picking red, blue and green balls respectively. The probability of picking any of the green balls are equivalent since only one ball of each colour should be picked. The detailed solution is found in the image attached. They are independent events so we multiply the probabilities.

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 > -10.55
