Question

From a well shuffled standard pack cards,what is the probability that any card is drawn (a) diamond (b) club
(C) Heart (d) a 7

Answer 1

Answer:

Step-by-step explanation:

For the cards in a pack.

Let S be the sample space

n(S) = 52

Let A be the event that card drawn out is a diamond one.

n(A) = 13

Therefore P(A) = n(A) / n(S)

==> 13/52 = 1/4 or 25%

Let B be the event that card drawn is a club one

....(Very similar to first example since no. Of club cards are also the same = 13)

Let C be the event that card drawn is a heart

....(Very similar to first example since no. Of heart cards are also the same = 13)

Let D be the event that card drawn is 7

As there are 4 card of 7 in a pack of card...

n(D) = 4

P(D) = n(D) / n(S)

==> 4/52 = 1/13

Hope it helps you friend.
