Question

From a well shuffled pack of card a card is drawn randomly what is the probability of not getting a black card with number 8

Answer 1

n(A) = 2 ; n(S) = 52
so, 2/52
1- 2/52 =
50/52 or 25/26

Answer 2

Total no. of cards =52
=total no. of out comes
Total no. of black cards having no. 8
=2
=total no. of favourable cases.
Let the required probability be P(A).
Then
P(A)=(favourable cases)/(no. of outcomes)
=2/52
=1/26
P(A)=1/26
