Answer: 0.4
Step-by-step explanation:
If the height of the first bounce is 5.5, then you find what 60% of 5.5 is and to do that you do 60/100 and x/5.5 so cross multiply 60x5.5 to get 330 then divide by 100 to get 3.3 and you do that 5 more times to get 0.42768 which when rounded to the tenths place, gets you 0.4
The expected value of the game is its average earnings
- The expected value of a round is $2.23
- The expected value when the game is played 755 times is $1683.65
<h3>How to determine the expected value of a round</h3>
There are 12 cards with a value of 4 or less.
So, the probability of selecting a card with a value of 4 or less is:

The probability of selecting a card with a value more than 4 is the complement of the above probability.
So, we have:


The expected value is then calculated as:

Evaluate


Simplify

Hence, the expected value of a round is $2.23
<h3>The expected value when the game is played 755 times</h3>
In (a), we have:

In probability, we have:

So, we have:


Hence, the expected value when the game is played 755 times is $1683.65
