You toss a coin and roll a number cube. Find P(heads and an even number)

3 0

"and" means summe
P(coin)+P(cube)=1/2+1/6=0,666667
The chance to get head is always 1/2 no matter how often you toss the coin
And the chance to get a number when you roll a number cube is always 1/6

Did you mean that?

<span>there are 12 possible outcomes.
Heads - 1
Heads - 2
Heads - 3
Heads - 4
Heads - 5
Heads - 6
Tails - 1
Tails - 2
Tails - 3
Tails - 4
Tails - 5
Tails - 6

You want heads AND an even number, so that narrows it down to three.
Heads - 2
Heads - 4
Heads - 6

So thats 3/12 chance, which is simply a 25.00 percent chance.

Much simper way to do so is that are 4 outcomes if you don't count the numbers.
Heads - Even
Heads - Odd
Tails - Even
Tails - Odd

so you can also get 25.0% that way.</span>

How much interest would $1,000 earn in 1 year at an annual rate of 2% compounded annually

What is Compound Interest ?

The interest charged on a loan or deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The main distinction between compound and simple interest is this. If we examine our bank statements, we will typically see that our account is credited with interest on a yearly basis. Even though the principal remains the same, the interest changes annually. We can observe that interest rises over time. As a result, we can infer that the interest the bank charges is compound interest, or CI, rather than simple interest.
