Question

When a die is rolled three times, the probabily sum of numbers is priime less than 10?

Answer 1

Answer:

Step-by-step explanation:

solution

One die is rolled.

Sample space ={1,2,3,4,5,6}

n (s) = 6.

Now

let event A be the sum of numbers is primeless than 10

A = { (1,2), (2,3),(3,4),(4,1),(6,1),(5,2) }

n(A) = 6

Now

P(A) = n(A) % n(s)

= 6%6

= 1

Probability of sum of numbers is prime less than 10 is 1
