Jackson is making pancakes with three ingredients: flour, milk and eggs. 20% of the bottles of milk are spoiled and the rest are fresh. 60% of the eggs are rotten. 1/4 of the cannisters of flour have weevils in them. If Jackson picks a bottle of milk, an egg and a canister of flour at random, what are the odds all three ingredients will be good?
Let's think step by step.

First find the percentage of milk bottles that are fresh: 100% - 20% = 80%.

Then find the percentage of the eggs that aren't rotten: 100% - 60% = 40%.

Then find the fraction of the flour canisters that don't have weevils: 1 - 1 / 4 = 3 / 4.

Divide the numerator of this fraction by the denominator and multiply by 100% to convert from a fraction to a percent: 3 / 4 * 100% = 75%.

Then multiply the probability that each ingredient is good to find the probability they all are: 75% * 80% * 40% = 24%.

So, the answer is 24
