The first figure belоw shоws the distributiоn of аnnuаl incomes of people in some country in the form of а continuous probability density function. The shaded region corresponds to the area under the curve for x values above $24,960 (average income). A label shows the numeric value of this area.The second figure shows the same probability density function, but with the area under the curve for x-values above $15,700 shaded. Using these figures, what is the probability that someone earns between 15700 and 24960? Write in a number between 0 and 1 correct to two decimal places?
