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.

Find the greatest common factor of 18 and 35
Flura [38]

Hi,

Let's look at the factor list:

The factors of 18 are 1, 2, 3, 6, 9, and 18.

The factors of 35 are 1, 5, 7, and 35.

The only common factor is 1, so the greatest common factor is 1.

Have a great day!
