The probability of choosing cards either Q or R when a card is drawn from a deck of 8 cards is 0.25.
Given that a card is randomly chosen from 8 cards shown in figure.
We have to calculate the probability of choosing either Q or R when a card is drawn from those 8 cards.
Probability means calculating the likeliness of happening an event among all the events possible. It lies between 0 and 1. It cannot be negative.
Number of cards=8
Number of repeated cards=0
Number of cards showing Q and R =1 each.
Probability of getting Q or R is P(X=Q)+P(X=R)
= 1/8+1/8
=2/8
=1/4
=0.25
Hence the probability of getting either P or Q when a card is drawn from 8 cards is 0.25.

Answer: 62.5 percent
Step-by-step explanation:
First, let's find how many page's Greta read per day. She read a total of 900 pages across 15 days, so she read:
900 pages / 15 days = 60 pages/day
Now we can find how many pages she read per hour by dividing the 60 pages per day by 5 hours:
60 / 5 = 12 pages/hour
The answer is 12 pages.
Answer:
B. 520
Step-by-step explanation:
Partial quotient is simply the method used to find the value of a quotient by dividing bits by bits until you get to the answer. For instance if you want to divide 124/4
Whatever closest multiple of 4 to 124 you remember, write it down. For instance I remember 80 first.
80 is the 20th multiple of 4 (80÷4 = 20).
Then subtract the number from the original number you want to divide
124 – 80 = 44
Again, write down the closest multiple of 44 you remember. To me is 40, and it is the 10th multiple.
Subtract 40 from 44 you have 4 left.
It's now easy to divide 4 by 4 which is 1.
To now get the quotient in total, you'll add up
20 + 10 + 1 = 31.
Therefore, to use partial quotient in this problem, the best choice to begin with will be 520 because it is the 20th multiple of 26. Although 780 is the 30th multiple of 26, 520 will be easier to remember. For this reason, it is the best choice.
