Question

Two dice are thrown simultaneously . Find the probability of getting (i) an even no. as the sum (ii) the sum as a prime no. (iii)a total of atleast 10 (iv) a doublet of even no. (v) a multiple of 2 on one dice and a multiple of 3 on the other dice (vi) same no on both dice (vii) a multiple of 3 as sum

Answer 1

Total no. of outcomes=36
P(even number as sum)=`18/36`
P(sum as prime number)=`15/36`
P( a total of atleast 10)=`6/36`
P(doublet of even number)=`9/36`
P(a multiple of 2 on one dice and 3 on other)=`9/36`
P(same no. on both dice)=`6/36`
P( a multiple of 3 as sum)=`12/36`
