What is the probability of rolling two dices whose sum is prime
Nuetrik [128]

The logic is there are six sides to each die, so for each number on one die you can pair with six different numbers on the other die. Therefore, the probability of rolling a prime number on two dice is 15/36, which reduces to 5/12.

How do you solve this problem
djyliett [7]

Answer: Undefined

Step-by-step explanation:

For this problem, we know that 3ˣ=-9. All we have to do is figure out what x is.

We know that any integer raised to the power cannot be negative. The closest answer we can get is x=2 because 3²=9. Unfortunately, we are looking for -9. Therefore, this x is undefined.

Answer: There are 12 white and blue cars more than silver and red cars

Number of white cars: n1=25
Number of blue cars: n2=17
Number of white and blue cars: n3=n1+n2=25+17→n3=42

Number of silver cars: n4=21
Number of red cars: n5=9
Number of silver and red cars: n6=n4+n5=21+9→n6=30

How many more white and blue cars are there than silver and red cars?
n=?

n=n3-n6=42-30→n=12

Answer: There are 12 white and blue cars more than silver and red cars.
