Answer:

0.7699

Explanation:

The calculation of the probability that at least one stocks is shown below :-

∩ represents the interaction of sets.

while

∪ represents the set of all elements in the collections.

So,

P(A ∩ B) = P(B) × P(A ÷ B)

= 0.39 × 0.59

= 0.2301

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

= 0.61 + 0.39 - 0.2301

= 1 - 0.2301

= 0.7699

The income elasticity of demand for housing property is exactly 1.40. Due to a recession, you expect incomes to drop by 5% next
a_sh-v [17]

Answer:

Buy 7% less houses

Explanation:

Income elasticity of demand measures the responsiveness of quantity demanded to changes in income

Income elasticity of demand = percentage change in quantity demanded/ percentage change in income

1.40 = percentage change in quantity demanded/ 5%

Percentage change in quantity demanded = 1.4 × 5% = 7%

Because the coefficient of elasticity is greater than one, it means demand is income elastic. This means quantity demanded is responsive to changes in income. A fall in income would reduce the quantity demanded.

I hope my answer helps you
