Question

A card is selected from a deck. Find the probability that it is a 3 or a heart.

Answer 1

Answer:

The probability is (for 3) 4/52=1/13 and (for a heart) 13/52=1/4.

Answer 2

Answer:

A card is in selection in a deck of 52 card. The probability of getting 3 is $\frac{4}{52}=\frac{1}{13}$

The probability of getting a heart is $\frac{13}{52}=\frac{1}{4}$

Explanation:

Total cards in a deck = 52

Total number of 3’s in a deck = 4

i.e for every heart, spade, club, and diamonds, the number 3 will be counted and in total, it is 4.  

Total number of heart in a deck = 13

i.e for every suite ( heart, spade, clubs, and diamond, 13 cards will be there).

So, the total probability of having 3’s in a deck $=\frac{4}{52}=\frac{1}{13}$

The total probability of having the heart in a deck $=\frac{13}{52}=\frac{1}{4}$
