Answer 2

Step-by-step explanation:

Black Cards-  4

White Cards-  3

Red Cards   -  7

Total Cards  -  14

a)Red Card             ---   Favourable Outcomes/Total no of outcomes

                                =       7/14 = 1/2

b)Black Card           ---         Favourable Outcomes/Total no of outcomes

                                 =         4/14 = 2/7

C)White Card           ---        Favourable Outcomes/Total no of outcomes

                                 =          3/14

d) Red or White Card ---         Favourable Outcomes/Total no of outcomes

                                 =           7+3/14   = 10/14  = 5/7

∴ Thus, the probability of :-

     Red Card                 = 1/2

     Black Card               = 2/7

     White Card               = 3/14

     Red or White Card   = 5/7
