What is the probability that the first three cards drawn from a full deck of cards are kings are kings

1/5525

Step-by-step explanation:

Required outcome = Number of kings in a deck = 4

Assume card is drawn without replacement :

Number of cards In a deck = total possible outcomes = 52

Probability = required outcome / Total possible outcomes

P(first draw is a king) = 4 /52 = 1/13

P(secind draw is a king) = 3 /51

P(third draw is a king) = 2 /50

P(first three cards is a king) :

1 /13 * 3/51 * 2/50 = 6/33150 = 1/5525

the answer is 489

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
