Question

Two dices are thrown
C is the event that the sum the sum of upper most face is divesible by 5.​

Answer 1

Answer:

Step-by-step explanation:

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)}

Therefore, n(S)=36

C is the event that sum of the numbers on their upper face isDIVIDED BY 5

∴C={(4,6),(4,1),(2,3),(3,2),(4,1),(6,4),(5,5),  

⇒n(C)=7

SO THE PROBABILITY IS  7/36
