Answer:

a) P = 0.125

b) It is not necessarily true

Step-by-step explanation:

a. If the coin was fair, the probability of obtaining head would be 0.5, and each launch of the coin would be an independent event.

Remember that if two events A and B are independent, then:

P(A∩B) = P(A)P(B)

Therefore, the probability that Caitlin would get heads on all three flips is:

P(A∩A∩A) = P(A)P(A)P(A) = 0.5*0.5*0.5 = 0.125

b) It is not necessarily true, because there exist a probability associated to this event and it means that this situation can occur although the coin was fair.

BRAINLIESTTT ASAP!!! PLEASE HELP ME :)<br><br> Explain your answer please and show your steps/work.
algol [13]

Answer:

√x

Step-by-step explanation:

First, simplify -3⁄6 to -½. Next, according to the Negative Exponential Rule, move the denominator to the numerator to get x¹\²:

bⁿ = 1\b⁻ⁿ

Then, according to the Definition of Rational Exponents [part I], rewrite this as a radical, which in this case would be √x. This is when your numerator is 1:

ⁿ√aᵐ = aᵐ\ⁿ

**I have a video that explains all six exponential rules. It is titled "Six Exponential Procedures". I encourage you to watch the video and gain alot more knowledge from it, so you can better understand the concept.
