Question

two dice are rolled simultaneously find the probability of total is a prime number​

Answer 1

$\frac{4}{6} \times \frac{4}{6}$

$= \frac{16}{36}$

Answer 2

Answer:

5/12

Step-by-step explanation:

Sample Space (S)= {1+1, 1+2.....6+6}

n(S)=36

E=  Sum of rolls should be a prime number

E={1+1, 1+2, 2+1, 3+2, 2+3, 4+1, 1+4, 4+3, 3+4, 6+1, 1+6, 2+5, 5+2, 6+5, 5+6}

n(e)= 15

P(e)= 15/36=5/12
