1.	find the probablity of one card draw in 52cards. draw card diamond or Ace.
Answer» total number of cards = 52Number if ace = There are 4 Ace Cards in a deck. Number of diamond = There are 13 cards Let event 'A' be drawing a ‘Diamond’, then probability of getting a ‘Diamond', P(A) = 13/52 Let event 'B' be drawing an 'Ace’, then probability of getting an ‘Ace’, P(B) = 4/52 Probability of getting Ace of Diamond, P(A and B)= 1/52 Probability of getting a ‘Diamond' or an ‘Ace’ if one card is drawn at random,P(A or B) = P(A) + P(B) — P (A and B) = 13/52 + 4/52 — 1/52 = 4/13

find the probablity of one card draw in 52cards. draw card diamond or Ace.

Answer»

total number of cards = 52Number if ace = There are 4 Ace Cards in a deck.

Number of diamond = There are 13 cards

Let event 'A' be drawing a ‘Diamond’, then probability of getting a ‘Diamond', P(A) = 13/52

Let event 'B' be drawing an 'Ace’, then probability of getting an ‘Ace’, P(B) = 4/52

Probability of getting Ace of Diamond, P(A and B)= 1/52

Probability of getting a ‘Diamond' or an ‘Ace’ if one card is drawn at random,P(A or B) = P(A) + P(B) — P (A and B) = 13/52 + 4/52 — 1/52 = 4/13
