You roll a die. If an odd number comes up, you lose. If you get a 6, you win $60. If it is aneven number other than 6, you get t

vitfil [10]

Answer:

Step-by-step explanation:

Given that if an odd number comes up, you lose.

i.e. $P(losing) = P(1,3,5) = \frac{1}{2}$

$P(win 60) = P(6) =\frac{1}{6} \\$

If you get 2 or 4 you roll again

Thus rolling again prob = $\frac{2}{6} =\frac{1}{3}$

After rolling II time, if get 6, win otherwise lose.

Thus winning amounts A canbe

0 36 60

$P(0) = \frac{1}{2}+\frac{1}{3} (\frac{5}{6})=\frac{7}{9} \\P(36) = \frac{1}{3} (\frac{1}{6})=\frac{1}{18}\\P(60) =\frac{1}{6}$

This is a genuine pdf since prob >0 and total prob = 1.

b)Expected gain = sum of gain * prob = $\frac{7}{9} (0)+\frac{1}{18} (36)+\frac{1}{6} (60)\\=12$

Thus I would be willing to pay an amount atmost 12 dollars.

What is a formula to calculate the area of cross section when the figure is in circular shape

Naddik [55]

Answer:

Area for cross-section is 615.7521601cm

Step-by-step explanation:

area of a circle = πr²

π × radius²

In this question, the radius is 14, so you need to square it giving 196.

Then multiply by π = 615.7521601cm (round if necessary)
