In Example 124, P(X=Y), is

A

`(11)/(36)`

B

`(1)/(3)`

C

`(13)/(36)`

D

`(1)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`P(X=Y)=P(D_(1) cap D_(2)) cup (W_(11) cap W_(22)) cup (W_(12) cap W_(21))`
`=P(D_(1) cap D_(2))+P(W_(11) cap W_(22))+P(W_(12) cap W_(21))`
`=P(D_(1))P(D_(2))+P(W_(11))P(W_(22))+P(W_(12))P(W_(21))`
`=(1)/(6)xx(1)/(6)+(1)/(2)xx(1)/(3)+(1)/(3)xx(1)/(2)=(13)/(36)`
