Answer:

Option A

Step-by-step explanation:

<h3>Arithmetic sequence:</h3>

In a arithmetic sequence, difference between any two consecutive term is constant.

a₁ = 9 & d = 7

t₁ = 9

t₂ = a₁ + d

= 9 + 7

= 16

t₃ = t₂ + d = 16+ 7

= 23

t₄ = t₃ + d

= 23 + 7

= 30

t₅ = t₄ + d

= 30 + 7

= 37

9,16,23,30,37,.......

#10-1 : What is the probability of randomly choosing a diamond card from a regular deck of 52 cards? What is the probability of

Alchen [17]

$\huge{\boxed{\frac{1}{4}}}\ \ \huge{\boxed{\frac{1}{4}}}$

There are $13$ of each suit in a deck of $52$ cards.

This means the probability of drawing a diamond card is $\frac{13}{52}$ . You can divide the numerator and denominator each by $13$ to simplify. $\frac{13}{52} \div \frac{13}{13} = \boxed{\frac{1}{4}}$

Since there are the same number of clubs as there are diamonds, the probabilities are the same.
