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

= \frac{4!}{3! ( 4-3)!}

= 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 = _4 C_3 × 0.2³ × ( 1- 0.2)

probability = 4 × 0.008 × 0.8

probability = 0.0256

A stock produced returns of 14 percent, 17percent, and -1 percent over three of the past four years, respectively. The arithmeti
mariarad [96]

Answer:

11.23%

Explanation:

Arithmetic return = Total return/Total time period  

6% = (14% + 17% - 1% + x%) / 4

(6%*4) =30% + x

24% = 30% + x

x = (24% - 30%)

x = -6%

<em>For the standard deviation, we need to use </em><u><em>stdev.s function</em></u><em> in Ms Excel</em>

Standard deviation = stdev.s (14%,17%,-1%,-6%)

Standard deviation = 0.112249722

Standard deviation = 11.23%

So, the standard deviation of the stock's returns for the four-year period is 11.23%.
