Based on the students who passed, the probability that a random student gets an A in Statistics or Psychology or both is 0.226.

The probability that a random student did not get an A in Psychology is 0.84.

<h3>What are the probabilities of getting an A in psychology?</h3>

In order to find out the probability that a person got an A in either Statistics, Psychology, or both, the formula is:

= Probability of A in Psychology + Probability of A in Statistics - ( Probability of A in Psychology and Statistics)

= (80 / 500) + (82 / 500) - ( 49 / 500)

= 0.16 + 0.164 - 0.098

= 0.226

The probability of not getting an A in Psychology is:

= 1 - Probability of A in Psychology

= 1 - (80 / 500)

= 0.84

Answer:

d. nominal GDP is $500, real GDP is $400, and the GDP deflator is 125.

Explanation:

Real GDP is total output produced in an economy within a given period multiplied by base year prices

Nominal GDP is the sum of all final goods and services produced in an economy within a given period multiplied by current year prices.

Nominal GDP = (100 × $3) + (50 × $4) =

$500

Real GDP = (100 × 1.5) + (50 × $5) = $400

GDP deflator = (nominal gdp / real gdp) x 100

(500 / 400) × 100 = 125
