A die is rolled twice. What is the probability of showing a 1 on the first roll and an even number on the second roll?
Ivan

Answer:

1/12

Step-by-step explanation:

Okay, so this will be a compound probability question because there are two parts to the question.

Firstly, a die has 6 sides, and there is only one chance of getting a 1, so the probability would be 1/6.

Furthermore, there are 3 different even numbers on a 6-sided die, so that is 3/6, which can be simplified to 1/2.

Now, because this is a compound probability, we have to multiply 1/2 and 1/6 together, which would give us our answer of 1/12.

Double angle identity. Just 5 questions. Really need help as my teacher has been frustrated with me
BartSMP [9]

The double angle identities are

\sin(2x)=2\sin x\cos x

\cos(2x)=\cos^2x-\sin^2x

Then

2\sin\dfrac\pi6\cos\dfrac\pi6=\sin\left(\dfrac{2\pi}6\right)=\sin\dfrac\pi3

\cos^2\dfrac\pi{10}-\sin^2\dfrac\pi{10}=\cos\left(\dfrac{2\pi}{10}\right)=\cos\dfrac\pi5

The second identity together with the Pythagorean identity, \sin^2x+\cos^2x=1, gives us another equivalent expression:

\cos^2x-\sin^2x=\cos^2x-(1-\cos^2x)=2\cos^2x-1

so

2\cos^2(0.5)-1=\cos(2\cdot0.5)=\cos1
