Aroulette wheel has 15 red slots, 15 black slots, and 2 green slots. when it is spun, a metal ball has an equal chance to land in each slot. a bet on red pays even money, i. e., if the ball lands in a red slot you win an amount equal to your bet and if the ball does not land in a red slot you lose the amount you bet. you come to the roulette wheel with only $1, which you bet on red. you continue to bet all of your money on red each time the wheel is spun, until you lose. let x be the number of spins up to and including the time that you lose. what is var(x)?

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
