Can someone please help?

I answered the 1st one on your other post

2nd: 1/8

3rd: I don't know anything about inchwe study in cm so I don't know the answer

Step-by-step explanation:

we throw a coin. it has 2 probabilities: heads or tails

each probability is 1/2

1st throw 1/2

2nd throw 1/2

3rd throw 1/2

as all these throws are independent from one another, we put × between them. so: 1/2 ×1/2 ×1/2= 1/8

correct answer:

i^31 = -i
