Answer:
2.1
Step-by-step explanation:
The expected value of a probability is given by the formula:
E(x) = Σxp(x)
Therefore from the table showing the winnings of a game, the expected value of the probability distribution is:
E(x) = Σxp(x) = (0 * 0.5) + (2 * 0.2) + (4 * 0.15) + (6 * 0.1) + (10 * 0.05)
E(x) = 0 + 0.4 + 0.6 + 0.6 + 0.5 = 2.1
Hence we can conclude that the expected value of the winnings of the game is 2.1.

Step-by-step explanation:
just add corresponding position integers to each other
Let's use ratio and proportion or rates to solve this
If there is 5/6 cup of cinnamon in a 3/4 pound of spice mix, how many are in a pound?
5/6=3/4
?=1
1/ (3/4)*5/6=10/9
Therefore there are 10/9 cups of cinnamon in 1 pound of spice mix
