Question

a card is drawn at random find the probability of getting spade or an ace​

Answer 1

Answer:

Formula : P( AUB ) = P(A) + P(B) - P ( AnB))

P(A) = getting spade card

number of expect possiblity = 13

• P (A) = 13/52

P(B) = getting ace card

number of expect possiblity = 4

• P (B) = 4/52

P(AnB ) = getting ace of spade

number of expect possiblity = 1

• P(AnB) = 1/52

Answer = 13/52 + 4/52 - 1/52

= 16/52
