You have seven cards, numbered 3 through 9, and you pick one at random. If you pick a card with a prime number, you get 1 point;

Roman55 [17]

Answer:

He has $\frac{-1}{7}$ number of points

Step-by-step explanation:

We have given that numbers from 3 to 9

So numbers will be 3,4,5,6,7,8,9

Here prime numbers are 3,5,7

And composite numbers are 4,6,8,9

So probability of getting prime number = $\frac{3}{7}$

And probability of getting composite number $=\frac{4}{7}$

It is given that if he gets prime number then he get 1 point and if he get composite number then he loss 1 point '

So value of number of point he has = $1\times \frac{3}{7}-1\times \frac{4}{7}=\frac{-1}{7}$

Anyone have any tricks to make quadratic functions less-intimidating? I’m a bit confused with all the numbers and rules.

Try to find ways that you can easily remember formulas. For example, when you find the line of symmetry the equation is y=-b/2a. A way you can remember that is by saying negative tuba. It seems silly but it’s something you can do for most equations so it doesn’t seem so intimidating.
