Question 1 There's a. box in front of you with a button. You know that each time you press the button the button will turn green % of the time and it will turn red all other times? Each game consists of you pressing the button 15 times and you lose the game if the red light appears exactly 14 times What is the probabit].r that you win {exactly} 5 out of 15 games? (Would you personally play this game?)
