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.

Expand the number 1120 into its corresponding exponential form. 25 · 5 · 7 52 · 8 22 · 53 · 7 2 · 5 · 7
Eduardwww [97]

Answer:

(A) 2^{5} * 5 * 7

Step-by-step explanation:

Your question formatting made it very complicated to understand the possible answers.  Please use some notation or the equation editor next time.

So, the exponential form a way to write a number using multiplications and powers.

Let's examine the various options (if I read them correctly)

(A) 2^{5} * 5 * 7 - YES!

2^{5} is 32, so 32 * 5 * 7 = 160 * 7 = 1120

(B) 5² · 8  - NO

= 25 * 8 = 200

(C) 2² * 5³ * 7 - NO

= 4 * 125 * 7 =500 * 7 = 3500

(D) 2 · 5 · 7 - NO

= 10 * 7 = 70
