Answer:

4/52 or 1/13

Step-by-step explanation:

In a standard deck of 52 cards, there are 4 suits and each suit has 13 cards.

There are 4 kings, 4 queens, 4 aces, and 4 jacks.

So the probability of drawing a king would be:
4/52 = 1/13

Answer:

The probability of drawing a King is 4/52 or about . 0769, which is also the probability of drawing a Queen. The probability that a card drawn from the deck will be both a King and a Queen is zero. The probability that a card will be either a King or a Queen is 8/52.

Step-by-step explanation:

52 cards in a deck 4 queens and 4 kings

igor_vitrenko [27]

Answer:

0.27, 0.42, 0.7 & 0.22, 0.4, 0.72

Step-by-step explanation:

decimals 0.7 0.27 0.43 from least to greatest. Do the same thing with 0.4 0.22 0.72 what are your answers?

Arranging in ascending order ( 0.7,0.27,0.42) would be 0.27, 0.42, 0.7

This is gotten If all these decimals are converted to fractions with their denominator being 100 that is 27/100, 42/100, 70/100

Arranging in ascending order(0.4,0.22,0.72) would be 0.22, 0.4, 0.72

This is gotten If all these decimals are converted to fractions with their denominator being 100 that is 22/100, 40/100, 72/100

Evaluate the summation of 3 times negative 2 to the n minus 1 power, from n equals 1 to 5.

Zanzabum

The answer is <span>C.33
</span>
3 * (-2)ⁿ⁻¹
n = 1; 3 * (-2)¹⁻¹ = 3 * (-2)⁰ = 3 * 1 = 3
n = 2; 3 * (-2)²⁻¹ = 3 * (-2)¹ = 3 * (-2) = -6
n = 3; 3 * (-2)³⁻¹ = 3 * (-2)² = 3 * 4 = 12
n = 4; 3 * (-2)⁴⁻¹ = 3 * (-2)³ = 3 * (-8) = -24
n = 5; 3 * (-2)⁵⁻¹ = 3 * (-2)⁴ = 3 * 16 = 48

The sum is:
3 + (-6) + 12 + (-24) + 48 = 3 - 6 + 12 - 24 + 48 = 33

Cloud [144]

Answer:

80 countries participated in the 1980 olympics in Moscow.

Step-by-step explanation:

Hello, I think I can help you with this

You can solve this by using a simple rule of three

Step 1

define

140 countries participated in 1984,this was 75% more than the last time,this means that 140 is the 175% of a value that we need to know

140 ⇔175%

x? ⇔100%

the relation is

$\frac{140}{175}=\frac{x}{100}$

Step 2

solve for x

$\frac{140}{175}=\frac{x}{100}\\x=\frac{100*140}{175}\\x=\frac{14000}{175} \\x=80$

80 countries participated in the 1980 olympics in Moscow.

Have a nice day
