If an unfair coin is tossed into the air and drops without interruption, its probability of landing on heads is 0.51 whereas the probability of landing on tails is 0.49. If the payoff for landing on heads is $0.99 and the payoff for landing on tails is $1.01 and it costs $1 to play each game, should you play?1)Yes, because over the long run your expected value is greater than the lowest payoff2)No, because over the long run your expected value is lower than the lowest payoff3)Yes, because over the long run your expected value is greater than the cost to play4)No, because over the long run your expected value is less than the cost to play

PLZZZZ HELP SOONWILL MARK BRAINLIESTGet ready for the launch of America’s Top Equation!Imagine that a TV network held a talent contest for . . . equations. Which type of equation would you want to win? Pick the kind of function that you’d like to sponsor for the contest, and describe its traits in a way that shows why it should be America’s top equation.Recall some of the types of equations: linear, exponential, and quadratic (you’ve seen these equations applied to increasingly advanced scenarios), plus polynomial, radical, and rational. You’ve seen these equations in systems and by themselves, and sometimes as the basis of an inequality or a system of inequalities.In your description, include key features (as represented in a graph, equation, or table) and prove your equation type’s worth for solving real-world problems. America’s top equation must prove useful and applicable to everyday situations!
