Answer:

23. 8n - 9

24. 55 - 45n

25. 69a - 10

26. -30m + 33

27. -4 + 96x

28. -8n + 26

29. -25b - 20

30. -71n - 9

Step-by-step explanation:

23. -2n - 9 + 10n

Collect like terms

= 8n - 9

24. 10 - 45n + 45

Collect like terms

= 55 - 45n

25. 9a + 60a - 10

Collect like terms

= 69a - 10

26. -54m + 27 + 6 + 24m

Collect like terms

= -30m + 33

27. -10 + 90x + 6x - 60

Collect like terms

= -4 + 96x

28. -10n + 20 + 2n + 6

Collect like terms

= -8n + 26

29. -30b - 30 + 5b + 10

Collect like terms

One card is randomly selected from a deck of cards find the odds against drawing a seven
Stella [2.4K]

Answer:

\frac{3}{4}

Step-by-step explanation:

Probability of getting a 7 + Probability of not getting a 7 = 1.

Odds against drawing a 7 = Probability of not getting a 7.

We could calculate the probability of getting a 7 and subtract 1 from it to get the answer.

There a four sevens in a deck of card, one of each kind.

Probability of getting a 7 = $ P(7) = \frac{4}{52} = \frac{1}{13} $

$ \implies P(not \hspace{1mm} getting \hspace{1mm} a \hspace{1mm} 7) = 1 - P(7) $

$ \implies $ P(not getting a 7) $ = 1 - \frac{1}{13} = \frac{12}{13} $
