Question

Dolly is a careless child so, she losses an Ace Spade out of a deck of 52 cards. Now what is the probability of sunny  getting a black card from the remaining pack.
1. 1/13
2. 25/52
3. 25/51
4. 1/2
5. 26/51

Answer 1

Correct Answer - Option 3 : 25/51

Given 

Ace Spade is lost.

Concept used

P(E) = Favourable outcomes / Total outcomes

Calculation

As a Spade has lost, 

Total number of cards = 52 -1 = 51.

Total number of black cards = 26 - 1 = 25.

P(Black Card)  = 25/51

⇒ Probability of getting a Black Card = 25/51

∴ Required answer is 25/51.
