class10 plz reply the correct answer​

Answer 1

Step-by-step explanation:

1)

For two dice to multiply to 12 we have four options: (2,6),(3,4),(4,3) and (6,2)

There are 36 possibilities altogether when rolling two dice. Since there are only 4 possibilities for getting 12, this means we have

4/36 i.e. 1/9 probability of getting a product of 12 when 2 dice are thrown.

2) Total no. of cards =52

(a) No. of face cards =12

So,

Face card)= 12/52

= 3/13

Thus,

Non-face card =1− 3/13 = 10/13

(b) No. of black kings =2

No. of red queen =2

No. of a black king and red queen =2+2=4

Thus,

Black king or red queen= 4/52= 1/13

ANSWER:- 1) 1/9

2)

a) 10/13

b) 1/13
