Answer:
Step-by-step explanation:
When the three cards are removed, the sample space becomes 49.
Probability of a heart = 13/49. No hearts were removed from the deck.
Probability of a king = 3/49. One king was removed from the deck.
Probability of the 10 of hearts = 1/49. There's only one 10 of hearts in the deck, and it was not removed.
Probability of a black face card = 3/49. Three of the black face cards were removed, so all that is left are the king, queen, and jack of clubs.
Probability of an ace OR a queen = 7/49 = 1/7. There are 3 queens and 4 aces remaining in the deck.
Answer:
279 × 7 ≈ 2800
Step-by-step explanation:
if you have to round to the tens place, then both would be rounded up, the 7 to 10 and the 279 to 280. 10 × 280 = 2800
Answer:
4) d = 60; e = 90
5) f = 30
6) h = 120
Step-by-step explanation:
4)
d + d + d = 180
3d = 180
d = 60
e + e + e + e = 360
4e = 360
e = 90
5)
70 + (180 - 100) + f = 180
70 + 80 + f = 180
f = 30
6)
45 + 75 + (180 - h) = 180
300 - h = 180
-h = -120
h = 120
