Answer:
For problem 31: 25 counters in the 5th figure, 81 counters in the 9th figure, and 121 counters in the 11th figure.
Step-by-step explanation:
Since in the examples it shows 1 exponent 2, 2 exponent 2, and 3 exponent 2, that means all the rest will have 2 as an exponent. So the fifth figure would be 5 exponent 2, which is 5 times 5 = 25. The 9th figure would be 9 exponent 2, which is 9 times 9 = 81. The 11th figure would be 11 exponent 2, which is 11 times 11 = 121.
Is that all, or do you need answers for #'s 32, 33, and 34?

Answer:
0.0625 = 6.25% probability that the first card drawn is a diamond and the second card is a club
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of independent events:
The probability of independent events happening at the same time is the multiplication of the probabilities of each events.
First card:
A standard deck has 52 cards, of which 13 are diamonds. So
Second card:
The first card is replaced, so still 52 cards, of which 13 are clubs. So
What is the probability that the first card drawn is a diamond and the second card is a club?
Each drawing is independent, so
0.0625 = 6.25% probability that the first card drawn is a diamond and the second card is a club
