Question

32. When two dice are thrown, What is the probability of getting a) Prime no
on both b) a sum of 10​

Answer 1

Answer:

event: two dice are thrown

sample space(s)=

{(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),

(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),

(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),

(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),

(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),

(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)}

n(s)=36

Step-by-step explanation:

Event (A): prime no. on both

(S)= {(3,3),(3,5),(5,3),(5,5)}

n(S)= {4}

Event (B): A sum of 10

(S)= {(4,6),(5,5),(6,4)}

n(S)= {3}
