Question

2 dice are thrown together . Find the probability of getting : a) a doublet of odd numbers , b) a sum of 7 , c) a prime number as a product

Answer 1

Answer:

when two dice are thrown you should know the outcome table

Step-by-step explanation:

when you get doublet of odd no.s

you would be like this(1,1),(3,3)and (5,5)

nP(A)=3

total n P(S)= 36

therefore

probality=3/36=1/12

[2]to get product as a prime number .

sample space=

(2,1),(1,3),(1,5),(3,1),(5,1)

here you cannot conside as (1,1) because 1 is neither prime nor composite .

so,leg A be the event

n(A)=5

total possibilities=36

P(A)=5/36.

hope you would get help with my answer
