Question

two cards are drawn at random from 8 cards number 1to
8 what is the probability that the sum of number is even if the two cards are drawn together

Answer 1

Answer:

1/2

Step-by-step explanation:

                                          S=1,2,3,4,5,6,7,8

                                          n(s)=8

                                           Let p(A) be probabilty of getting a even number

                                             A=2,4,6,8

                                            n(A)=4

                                            p(A)=4/8=1/2

Answer 2

probability=no of favorable outcomes

divide by

no of outcomes

here no of favourable outcome is 1

no of possible outcomes are 4(4 even nos from 1 to 8)

and 2 cards are drawn

so 1÷4×2

=1by2
