Answer:

The correct answer is "0.0000039110".

Step-by-step explanation:

The given values are:

$Y_n\rightarrow N(\mu, \sigma^2)$

$\mu = 40n$

$\sigma^2=100n$

$n=20$

then,

The required probability will be:

= $P(Y_{20}>1000)$

= $P(\frac{Y_{20}-\mu}{\sigma} >\frac{1000-40\times 20}{\sqrt{100\times 20} } )$

= $P(Z>\frac{1000-800}{44.7214} )$

= $P(Z>\frac{200}{44.7214} )$

= $P(Z>4.47)$

By using the table, we get

= $0.0000039110$

Compute the probability of event E if the odds in favor of E are (A) StartFraction 20 Over 27 EndFraction (B) StartFraction 25 O

vovikov84 [41]

Answer:

A) 0.4255

B) 0.5813

C) 0.5588

D) 0.7241

Step-by-step explanation:

Assuming that the probability for each case is the same, we can calculate the probability by dividing the number of favourable cases with the total amount of cases. You can find the total amount of cases by adding the favourable ones with the non favourable ones, so, the probability of each case would be:

A) 20/(27+20) = 20/47 = 0.4255

B) 25/(18+25) = 25/43 = 0.5813

C) 19/(15+19) = 19/34 = 0.5588

D) 21((8+21) = 21/29 = 0.7241
