Answer:
The probability that a coin flip is a head or a tail is 0.5. The probability that a coin flip is either a head or a tail is 1. The probability that a three-coin-flip is two heads and a head or a tail is 0.25.
Step-by-step explanation:
I'm assuming you meant to write 8^(-2) or
where the -2 is the exponent over the 8.
If my assumption is correct, then we use the rule 
So,

<h3>Answer: Choice D. 1/64</h3>
Answer:
Step-by-step explanation:
3/4 x 9/4 = 1.6875 or 27/16
The experimental probability is the number of specific outcomes divided by the sample size...
P(6)=27/100 (27%)
P(H)=41/100 (41%)
Not sure, but if you meant rolling a 6 AND getting a head then:
P(6 AND H)=(27/100)(41/100)=1107/10000 (11.07%)
Step-by-step explanation:

But we know that

and

so this leaves us with just
