If $A$ and $B$ throw a die each. The probability that $A s$ throw is not greater than $B s$ throw is $K /12$ , then $K =$

Answer:

Solution:

If A gets 1 , then Bs chances are $1, 2, .6 = 6$

If $A$ gets 2 , then $B$ s chances are $2, 3, \dots = 5$

Similarly so on up to $6 = \sum 6$

$∴ P (E) = \frac{21}{36}$
