Question

A pair of fair dice is rolled once find the probability mass function to get the number of fours​

Answer 1

Answer:

Step-by-step explanation:

When a pair of dice is thrown,

n(s)=6×6=36

and,

E= event of getting a sum of 8

   ={(2,6),(3,5),(4,4),(5,3),(6,2)}

∴n(E)=5

then,

P(E)=  

n(S)

n(E)

​  

=  

36

5
