I HAVE ANOTHER METHERD

Total cards= 21

Total cards= 21Birthday cards= 14

Total cards= 21Birthday cards= 14Rest of them= 21-14

Total cards= 21Birthday cards= 14Rest of them= 21-14=7

Total cards= 21Birthday cards= 14Rest of them= 21-14=7Ans- The cards which are not birthday cards is 7

I hope it's help u thank

Answer:

Probability of not a birthday card P(E2) = 0.33.

Step-by-step explanation:

Given :

The total number of cards in inventory of the company = 21.

Number of birthday cards = 14.

To find :

The probability of not getting a birthday card.

Solution :

Let S denote the total number of cards, E1 and E2 denote the event of getting birthday cards and not a birthday card.

The total number of cards in the inventory of the company, n(S) = 21.

Number of birthday cards , n(E1)= 14.

Then number of not a birthday card , n(E2)  = 21-14 = 7.

Let P denote the probability .

Probability of getting an event,

P(E)= Number of outcomes favourable to E

                 Total number of outcomes

Now, P( not getting a birthday card ) , P(E2) = n(E2)/n(s)

   Therefore,   P(not getting a birthday card), P(E2) = 7/21 = 1/3 = 0.33
