1.	A six-faced dice is so biased that it is twice as likely to show aneven number as an odd number when thrown. It is thrown twice, the probabilitythat the sum of two numbers thrown is even is`1//12`b. `1//6`c. `1//3`d. `5//9`A. `1//12`B. `1//6`C. `1//3`D. `5//9`
Answer» Correct Answer - D Let the probability for getting an odd number be p. Therfore the probability for getting an even number is 2p. `thereforep+2p=1orp=1/3` Sum of two numbers is even means either both are odd or both are even. Therefore, the required probability is `1/3xx1/3xx2/3xx2/3=1/9+4/9=5/9`
