Step-by-step explanation:
Flipping two fair coins :
Sample space :
{TH, HT, TT, HH}
Atleast one head = 12
If not = - 24
Probability of atleast one head = 3/4
If not ; probability of 2 tails = 1/4
Hence,
X ______12 ______ -24
P(x) ___0.75 ______0.25
Expected value for of gamble E(x) :
Σx * p(x) = (12 * 0.75) + (-24 * 0.25)
E(x) = 9 - 6
E(x) = 3
Expected value of gamble = $3
Let be "x" the number of hours of your work week you spend stocking shelves.
According to the information provided in the exercise, you work a total of 20 hours each week and you spend 3/5 of that time stocking shelves.
You can write that fraction as a decimal number by dividing the numerator by de denominator:

Then, to find the value of "x", you only need to multiply the total hours you work each week by 0.6.
Therefore, the result is:

You spend 12 hours of your work week stocking shelves.
