Paul went to a blackjack table at the casino. At the table, the dealer has just shuffled a standard deck of 52 cards.
Paul has had good luck at blackjack in the past, and he actually got three blackjacks with Kings in a
row the last time he played. Because of this lucky run, Paul thinks that Kings are the luckiest card.
The dealer deals the first card to him. In a split second, he can see that it is a black card, but he is
unsure if it is a King.
What is the probability of the card being a King, given that it is a black card? Answer choices are
in a percentage format, rounded to the nearest whole number.
8%
67% or 50% or 23%

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
