Question

You roll a cube with the numbers 13, 16, 18, 20, 22, and 24 on it. You then spin a spinner which has 6 sections. The letters on the spinner are E, B, G, K, D, and H. Find the P(G and prime number). Write your answer as a fraction or a decimal​

Answer 1

Answer:  1/36

===========================================================

Explanation:

The only prime number of the list of values given is the value 13. This is because the only factors are 1 and 13. Something like 24 isn't prime because 2 is a factor.

The probability of rolling to get a prime number is 1/6 because there is one prime out of 6 total values listed.

The probability of spinning on "G" is also 1/6 because there is only one section labeled "G" out of 6 sections total.

Assuming both events are independent, we multiply the probabilities to get (1/6)*(1/6) = 1/36 which represents the probability of rolling a prime number and spinning on G.

Side note: 1/36 = 0.0278 = 2.78% approximately
