Answer 2

estimate 6/7 + 8/9 = __

2
14/16
48/63
7/8

Answer 3

To estimate 6/7 + 8/9, we can use the fact that 6/7 is very close to 0.857 (rounded to three decimal places), and 8/9 is very close to 0.889 (rounded to three decimal places).

Therefore, 6/7 + 8/9 is approximately equal to 0.857 + 0.889 ≈ 1.746.

The closest option to this estimate would be 7/8.

Answer 4

in a standard deck of playing cards, one half of the care are red. there are 3 decks of cards. one card is dealt from each deck. what is the probability that all 3 cards are red?

Answer 5

In a standard deck of playing cards, one-half of the cards are red. This means that there is a 1/2 probability of drawing a red card from any given deck.

Since there are 3 decks of cards and we are drawing one card from each deck, the probability of drawing a red card from each of the 3 decks is (1/2) * (1/2) * (1/2) = 1/8.

Therefore, the probability that all three cards drawn are red is 1/8.
