Brian rolls 2 fair dice and adds the results from each. Work out the probability of getting a total that is prime.

Step-by-step explanation:

3 prime numbers out of 6 on each dice.

12 numbers combined between the 2 dice.

6/12= 50%

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
