Answer from: jonmorton159

probability that the card drawn is:

an ace or a king = 0.1538a king or a diamond = 0.3269

Step-by-step explanation:

Here we have , A card is drawn at random from a deck of 52 playing cards. We need to find that Find the probability that the card drawn is:

an ace or a king

A deck of standard 52 cards contain four aces. There are four kings in a standard deck of playing cards. So ,we need to find probability that card drawn is either a ace or king i.e.

$probability = \frac{Number-of-(ace+king)-cards}{total-number-of-cards}$

⇒ $probability = \frac{Number-of-(ace+king)-cards}{total-number-of-cards}$

⇒ $probability = \frac{8}{52}$

⇒ probability = 0.1538

a king or a diamond

A deck of standard 52 cards contain four kings. There are 13 Diamonds in a standard deck of playing cards. So ,we need to find probability that card drawn is either a ace or king i.e.

$probability = \frac{Number-of-(ace+king)-cards}{total-number-of-cards}$

⇒ $probability = \frac{Number-of-(ace+king)-cards}{total-number-of-cards}$

⇒ $probability = \frac{(13+4=17)}{52}$

⇒ $probability = \frac{(17)}{52}$

⇒ probability =0.3269

Therefore, probability that the card drawn is:

an ace or a king = 0.1538a king or a diamond = 0.3269

Answer from: salazarx062

a) The probability of drawing an ace or king = $\frac{2}{13}$

b) The probability of drawing a diamond or king = $\frac{4}{13}$

Step-by-step explanation:

Step 1 :

Total number of cards in the deck = 52

We need to compute probability that card drawn is

a) ace or king

b) King or diamond

Step 2 :

Number of ace in the pack = 4

Number of kings in the pack = 4

Hence the probability of selecting an ace or king = $\frac{8}{52}$ [total favorable divided by the total outcome] = $\frac{2}{13}$

Step 3:

Number of king in the card deck = 4

Number of diamond in the card deck = 13

Number of diamond cards which is a king = 1

Total number of cards that can be drawn ( king or diamond) = 4 + 13 - 1 = 16

Hence probability that a diamond or king is drawn = $\frac{16}{52}$ [total favorable divided by the total outcome] = $\frac{4}{13}$

Step 4 :

Answer :

a) The probability that card drawn is an ace or king = $\frac{2}{13}$

b) The probability that card drawn is a diamond or king = $\frac{4}{13}$

the answer is 62

Answer from: Quest

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

A. name the streets that are parallel to golden gate. b. name the streets that intersect 6th street.
