Evgesh-ka [11]

The probability that suits of cards are spades, hearts, and spades is 39/850 or 0.046.

According to the give question.

Three cards are drawn from a standard deck of cards without replacement.

Since,

The total number of cards in a standard deck = 52

Total number of spade cards = 13

Total number of heart cards = 13

Now,

The probabbility of getting first card as a spade card = 13/52 = 1/4

The probability of getting second card as heart card

= 13/(52 -1)     (cards are drawn without replacement)

= 13/51

The probability of getting third card as a spade card

= (13 - 1)/52 -2

= 12/50

= 6/25

Therefore, the probability that suits of the cards are spades, hearts, spades

= 1/4 × 13/51 × 6/25

= 39/850

= 0.046

Hence, the probability that suits of cards are spades, hearts, and spades is 39/850 or 0.046.

Step-by-step explanation:

BC is the bisector of \angle ABQ

\therefore \angle ABC \cong \angle CBQ..(1)\\\angle CBQ \cong \angle CAB..(2) \\(\angle 's\: in \: alternate\: segments) \\

From equations (1) & (2)

\angle ABC \cong \angle CAB\\\therefore AC = BC

(Because sides opposite to equal angles are equal)
