Basically, we are asked to find the price per ounce of the bag for each potato chip bag.
For the first one, the potato chip bag is 4 ounces and costs $0.96. To find the price per ounce for this bag, you'd have to divide the cost by the ounce. So:
1) $0.96 ÷ 4 = price per ounce
For the 4 ounce potato chip bag, you'd get the value of $0.24 per ounce.
Repeat this with the two other potato chip bags.
2) $3.25 ÷ 13 = price per ounce
$0.25 is the price per ounce for the 13 ounces potato chip bag.
3) $6.48 ÷ 24 = price per ounce
$0.27 is the price per ounce for the 24 ounces potato chip bag.
Compare the values. Which one has the lowest price per ounce and the highest price per ounce?
The lowest price per ounce is the potato chip bag with 4 ounces because it has the lowest value of $0.24 per ounce.
The highest price per ounce is the potato chip bag with 24 ounces because it has the highest value of $0.27 per ounce.
Solution: The 4 ounce bag has the best value because the price per ounce is $0.24. The 24 ounce bag has the worst value because the price per ounce is $0.27.
Probability of a tail for any on coin = 1/2 As the tosses of the 4 coins are independent of each other we multyiply the probs:- P(4 tails) = 1/2 * 1/2*1/2*1/2 = 1/16
