Answer: Fourth option is correct.

Step-by-step explanation:

Since we have given that

Total number of cards in deck = 52

Total number of face cards = 12

Number of cards are drawn = 2

Probability of getting at least one is holding a face card is given by

P(X=1)+P(X=2)

=\dfrac{^{12}C_1\times ^{40}C_1}{^{52}C_2}+\dfrac{^{12}C_2}{^{52}C_2}\\\\=\dfrac{12\times 40}{1326}+\dfrac{66}{1326}\\\\=\dfrac{480}{1326}+\dfrac{66}{1326}\\\\=\dfrac{546}{1326}\\\\=\dfrac{7}{17}

Hence, Fourth option is correct.

Is 976 -522 more or less than 400? Explain how you can tell without actually subtracting.
liq [111]
You can round 976 to 1000 and 522 to 500. So it would be
1000 - 500 = 500. The answer you would get after subtracting 976-522 would be more than 400 if you round it.

Write the numbers in order from greatest to least 7/10, 0.888, 3/5, 0.27
kvasek [131]
It would be 
.888,7/10,3/5,.27 
what you would do is convert 7/10 and 3/5 into a decimal to see what order you would place them and 7/10 as a decimal is .7 and 3/5 to a decimal is .6 so .888 is greater then it will be 7/10 then 3/5 then .27
