I think it A... But if it not sorry I didn’t help... hope this is the answer I am sure it is...
Answer:
![E.G=\$2](https://tex.z-dn.net/?f=E.G%3D%5C%242)
Step-by-step explanation:
Sample size 52 card
Pay for J or Q ![=\$17](https://tex.z-dn.net/?f=%3D%5C%2417)
Pay for King or Ace ![=\$5](https://tex.z-dn.net/?f=%3D%5C%245)
Pay for others ![=-\$2](https://tex.z-dn.net/?f=%3D-%5C%242)
Therefore
Probability of drawing J or Q
![P(J&Q)=\frac{8}{52}](https://tex.z-dn.net/?f=P%28J%26Q%29%3D%5Cfrac%7B8%7D%7B52%7D)
Probability or drawing King or Ace
![P(K or A)=\frac{8}{52}](https://tex.z-dn.net/?f=P%28K%20or%20A%29%3D%5Cfrac%7B8%7D%7B52%7D)
Probability or drawing Other cards
![P(O)=\frac{36}{52}](https://tex.z-dn.net/?f=P%28O%29%3D%5Cfrac%7B36%7D%7B52%7D)
Therefore
Expected Gain is mathematically given as
![E.G=\sum_xP(x)](https://tex.z-dn.net/?f=E.G%3D%5Csum_xP%28x%29)
![E.G=17*\frac{8}{52}+5*\frac{8}{52}+(-2)*\frac{36}{52}](https://tex.z-dn.net/?f=E.G%3D17%2A%5Cfrac%7B8%7D%7B52%7D%2B5%2A%5Cfrac%7B8%7D%7B52%7D%2B%28-2%29%2A%5Cfrac%7B36%7D%7B52%7D)

Answer:
<em>The amount of animal feed left was 86.4 kilograms.</em>
Step-by-step explanation:
Initial amount of animal feed in the barn was 96 kilograms.
The barn leaked and
of the feed was wasted.
So, <u>the amount of feed wasted</u>
kilograms.
<em>Now, for finding the amount of feed that was left, we need to subtract the amount of wasted feed from the initial amount of feed.</em>
So, the amount of animal feed left ![=(96-9.6)\ kilograms=86.4\ kilograms](https://tex.z-dn.net/?f=%3D%2896-9.6%29%5C%20kilograms%3D86.4%5C%20kilograms)
