In a certain game, we have to select one of three cards at random from an envelope. If we choose the green card, we win $120. If we pick the yellow card, we win nothing, and if we choose the red card, we lose $360. Assume that we are equally likely to pick any of the cards. How much money do we expect to win/lose on average

the answers c

you already gave the answer

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
