Answer:
A
Step-by-step explanation:
f(-3) = 2^-3
to get rid of a negative in an exponent, move the whole thing to the denominator.
1/(2^3)
2^3 = 2×2×2
1/(2×2×2)
1/8
Answer:
G
Step-by-step explanation:
"Any particular event either (a) will happen or (b) won't happen."
That statement above is a certainty, probability = 100% = 1
This means the probability that event E <u>will </u>happen plus the probability that even E <u>won't </u>happen must add up to 100% = 1
So we can always say --> prob(E) + prob (not E) = 1
The probability you will roll a 5 on a fair, six-sided die is 1/6.
So we use that to find the probability of not rolling the 5.
1/6 + prob(not E) = 1
prob(not E) = 1 - 1/6 <---- This is answer G
prob(not E) = 5/6
Hope this helps.
