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

I’m lost and unsure what is the first step to do find width of da roof
Monica [59]

Answer:

You set up an equation, using the trig function "tan" to find half of the roof (the equation would be tan(24) = 3.5/x, where x = 1/2 roof width)

Step-by-step explanation:

That would be the first step.

You solve the equation for x, and then multiply x by 2 to get the width of the roof.
