Answer: 1, 2, 3, 4, 5, 6

p greater than 2 = 4/6 = 2/3

p 2 or smaller and prime = 2/6 = 1/3

2/3 + 1/3 = 1

every single side of the cube is either greater than 2 or prime (two and one) so you simply will get the desired result in 100% of your rolls

Step-by-step explanation:

no of favourable cases, n(E) = 4

no of sample space, n(S) = 6

Probability that it will be rolled on the number greater than two, P(E) = n(E) / n(S) = 4/6 = 2/3

The count of bacteria in a culture is 10 and doubles every 20 minutes. Find the population size after 11 hours. Can someone expl
RSB [31]

Since you asked how to solve this, I will put the answer at the bottom.

You might not think the same way as I but I think in steps.

<h3>(1) Calculate how many times the bacteria divide in eleven hours</h3>

The bacteria divide every 20 minutes, and will therefore divide three times every hour, 60/20 = 3.

If the bacteria grow for eleven hours, each bacterium will divide 3 times per hour × 11 hours = 33 times.

<h3>(2) Add the orginial size of bacteria into the equation</h3>

(This part is edited)

(orginial size)*2^number of divisions

10*2^{33\\}
