Problem Analysis

A baker purchases flour from two different producers in a ratio of 40% to 60% respectively. The first producer has 37% high-grade flour, while the second producer has 41% high-grade flour. We need to find the probability that a randomly chosen package of flour in the bakery is high-grade flour.

Solution

To find the probability, we need to calculate the weighted average of the high-grade flour percentage from each producer based on their respective ratios.

Let's assume that the baker purchases 100 units of flour. This means that the first producer supplies 40 units (40% of 100) and the second producer supplies 60 units (60% of 100).

The first producer has 37% high-grade flour, so they supply 37% of the 40 units, which is 0.37 * 40 = 14.8 units of high-grade flour.

Similarly, the second producer has 41% high-grade flour, so they supply 41% of the 60 units, which is 0.41 * 60 = 24.6 units of high-grade flour.

The total amount of high-grade flour supplied by both producers is 14.8 + 24.6 = 39.4 units.

Therefore, the probability that a randomly chosen package of flour in the bakery is high-grade flour is 39.4 / 100 = 0.394, or 39.4%.

Answer

The probability that a randomly chosen package of flour in the bakery is high-grade flour is 39.4%.
