A) Two cards are drawn at random from a wel suffled pack of cards.given than both the cards are red,what is the probability that bothe cards are:-
1)having same no
<1> 9/325 <2> 64/325 <3> 144/325 <4> 28/325
2) diff no's on them and diff suits?
<1> 72/325 <2> 81/325<3> 144/325 <4> 28/325
B)four digit no's are formed using the digits 0 to 4 without repetion.the probabillity that a no so formed is divisible by 2 is
<1> 5/8 <2> 3/8 <3> 7/9 <4>2/9
ans: for A(1)-9/325
ans-for A(2)-72/325
ans:-for B-5/8
