The possiblities that exist:

H, H, H
H, H, T
H, T, H   <----
H, T, T
T, H, H
T, H, T
T, T, H
T, T, T

The answer is 1/8. Now the problem that you gave us isn't dependent upon anything, so more specifically the answer is 1/8 independent.

Nothing has actually happened therefore no odds have been decreased or increased.

Can you help me please!!!!
pentagon [3]
If you add the 3/4s with the 2 1/4 hour breaks it would be 1 hour and 1 fourth.
Then you take 10-1/2 hours and subtract it by 1 hour and 1 fourth.
So you would get 9-1/4 hours

PLS HELP ASAP find the measure of side b. round to the nearest whole number
ludmilkaskok [199]

Answer:

b=204

Step-by-step explanation:

The law of sine states that: \frac{SinA}{a} =\frac{SinB}{b} =\frac{SinC}{c}

We know that a triangle has 180° total, so we can subtract the two angle measures we know to find the third angle: 180-90-41=49°.

Using these two things, we can come up with the equality \frac{Sin90^{o} }{270} =\frac{Sin49^o}{b}, which we can use to solve for side b.

\frac{Sin90^o}{270} =\frac{1}{270}, so we know that \frac{1}{270} =\frac{Sin49^o}{b}.

Next, we would multiply both sides by b to get \frac{1}{270}b=Sin49^o.

Sin49°≈0.75471, so to find b we would multiply 0.75471×270=203.77

Since the problem asks us to round to the nearest whole number, b=204

Hope this helps! :)
