A coin is flipped three times. How does P(H, H, H) compare to P(H, T, H)?

Gekata [30.6K]

P(H,H,H)=P(H,T,H)

This is classical probability, so the probability of an event is the number of "favorable" events over total events.

The total number of events, by the counting principle, is 2^3=8.
The total number of events remains the same for P(H,H,H) and P(H,T,H), as you're still flipping 3 coins with two sides.

For P(H,H,H) the favorable event is (H,H,H) so 1, for P(H,T,H) the favorable event is (H,T,H) also one.

Conclusion:

P(H,H,H)=P(H,T,H)=1/8

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.

Find the area of the circle. Round your answer to the nearest hundredth 3in

FrozenT [24]

Answer:

28.26 square inches

Step-by-step explanation:

Formula for area of a circle:

$A=\pi r^2$

Radius is 3.

$A= \pi (3)^2\\A=\pi 9$

Use 3.14 for pi:

$A = 3.14 * 9 = 28.26\\A=28.26$

The area should be 28.26 square inches.

Answer:

Median

Step-by-step explanation:

This set of data has an extreme outlier, which will throw off the mean. The median, on the other hand, does not change or changes minimally whether or not the outlier is there.

By default, the mean is always better, but if an outlier, such as this one, is too large, the median is better.
