Since the probability of the coin landing leads is 1/2, simply cube 1/2 to arrive at your answer: 1/8.


You cube 1/2 because you must land heads three times in a row and each flip is independent from other flips.

Answer:

P(HHH) =  1/8

Step-by-step explanation:

The probability of getting heads is 1/2

P(H) = 1/2

We multiply the probabilities together because the events are independent.

P(HHH) = 1/2 * 1/2 * 1/2

             = 1/8

If f(n) = -6n + 2, find f (5/6)
joja [24]

f( \frac{5}{6} ) =  - 6( \frac{5}{6} ) + 2  \\ f( \frac{5}{6} ) = -  \frac{30}{6}  + 2 \\ f( \frac{5}{6} ) = - 5 + 2 \\ f( \frac{5}{6} ) = - 3

Answer:

No, she's wrong

x\leq\frac{2}{5}

Step-by-step explanation:

So starting from the beginning...

3x+3\leq -2x+5

Subtract the 3 from both side and it will look like...

3x\leq-2x+2

Then add 2x from both sides and it will look like...

5x\leq 2

Finally divide by 5 to both sides and it will look like...

x\leq \frac{2}{5}
