Answer:
probability = 0.008
probability = 0.0256
Explanation:
we know here probability of defective is 0.2
so probability of not defective is 1 - 0.2 = 0.8
as we know 3 item is arrive off process line in succession
so The probability that an item is defective is
as P(defective) = 0.20
as all item are independent so
probability that all three items are defective is
probability = 0.20 × 0.20 × 0.20 = 0.008
and
probability that exactly 3 of next 4 are defective
so number of way that can choose 3 out of 4 is
= 
= 4
so as all are independent probability is
probability = ( the number of way to choose 3 out of 4 ) × ( 3 item defective ) × ( 1 item not defective )
probability =
× 0.2³ × ( 1- 0.2)
probability = 4 × 0.008 × 0.8
probability = 0.0256
Answer:
a. 87.5%
b. Stock A: 21%; Stock B: 28%; Stock C: 38.5%; T-bill: 12.5%
c. Standard deviation of the client's portfolio: 26.25%
Explanation:
a. y is calculated as:
Risky portfolio return * y + T-bill return * (1 - y) = Expected return of the portfolio <=> 0.14y + 0.06 ( 1-y) = 0.13 <=> y = 87.5%
b. Client investment in each stock and in T-bills:
Client investment in each stock = 0.875 * percentage of each stock in a risky portfolio ( because the risky portfolio is accounted for 87.5% of the whole investment)
=> Stock A = 24% x 0.875 = 21% ; Stock B = 32% * 0.875 = 28% ; Stock C = 44 * 0.875 = 38.5%
Client investment in T-bill = 1- y = 1 - 0.875 = 12.5%
c. Standard deviation is calculated as: Standard deviation of risky portfolio * y = 30% * 87.5% = 26.25% (because standard deviation of return in T-bill is 0)
