Nettet17. jul. 2024 · Before you play the game you decide to find the expected value. You analyze as follows. Since a die will show a number from 1 to 6, with an equal probability of 1/6, your chance of winning $1 is 1/6, winning $2 is 1/6, and so on up to the face value of 5. But if the die shows a 6, you will lose $18. You write the expected value. Nettetwww.casact.org how to take off gel nail varnish
