Answer:
4.625 gallons
Step-by-step explanation:
1. 11 pints plus 13 quarts equals 18.5 quarts
2. 18.5 quarts corresponds to 4.625 gallons
These experiments depend on Bernoulli's principle. If the likelihood of "success" is p and you are looking for k successes out of n attempts, the probability can be expressed as:

To simplify the calculation for the first probability, instead of determining the chances of at least one subject having breakfast, we calculate the opposite: that none do. Thus, we seek 0 successes from 4 trials with a success probability of 0.34. Using the formula gives us:

With the contrary outcome at 17%, the probability of our event "at least one of the surveyed eats breakfast" is 83%.
Regarding the second question, the event "at least three of the surveyed eat breakfast" encompasses the events of "exactly three eating breakfast" and "exactly four eating breakfast." So, we just need to add their probabilities:

1.) Les composés carbonés sont fondamentaux pour tous les éléments organiques, constituant les bases de tous les organismes vivants.
2.) La forme allotropique du carbone en diamant est la substance la plus dure connue.
3.) Le carbone peut établir des liaisons covalentes avec d'autres atomes de carbone, formant ainsi des chaînes continues, des branches et des boucles.
To determine this answer, we would calculate 5.40 divided by 1.50 to ascertain the total cost of the fish at the supermarket.
5.4/1.5 = 3.6
Thus, the fish was priced at $3.60 in the supermarket.
