Ai Lun, a management trainee at a large New York based bank, is trying to estimate the real rate of return expected by investors
salantis [7]

Answer:

option B

Step-by-step explanation:

given,                                              

3-month T-bill currently yields  = 3%          

customer price have been rising = 2% rate

Ai Lun's estimate of the real rate = ?            

real rate return                                                  

                       = \dfrac{1 + risk\ free\ rate}{1 +inflation\ rate} - 1

                       = \dfrac{1 + 0.03}{1 +0.02} - 1

                       = \dfrac{1.03}{1 .02} - 1

                       = 1.0098 - 1

                       = 0.0098

                       = 0.98 % ≅ 1 %

hence, the correct answer is option B

What is the probability of rolling a number greater than or equal to 9 with the sum of two dice, given that at least one of the
olga55 [171]
Conditional probablility P(A/B) = P(A and B) / P(B). Here, A is sum of two dice being greater than or equal to 9 and B is at least one of the dice showing 6. Number of ways two dice faces can sum up to 9 = (3, 6), (4, 5), (4, 6), (5, 4), (5, 5), (5, 6), (6, 3), (6, 4), (6, 5), (6, 6) = 10 ways. Number of ways that at least one of the dice must show 6 = (1, 6), (2, 6), (3, 6), (4, 6), (5, 6), (6, 6), (6, 5), (6, 4), (6, 3), (6, 2), (6, 1) = 11 ways. Number of ways of rolling a number greater than or equal to 9 and at least one of the dice showing 6 = (3, 6), (4, 6), (5, 6), (6, 3), (6, 4), (6, 5), (6, 6) = 7 ways. Probability of rolling a number greater than or equal to 9 given that at least one of the dice must show a 6 = 7 / 11
