INFORMATION:
We know that:
- stack of mail consists of 8 bills, 10 letters, and 6 advertisements.
- One piece of mail is drawn at random and put aside. Then a second piece of mail is drawn.
And we must find P (both are letters)
STEP BY STEP EXPLANATION:
To find the probability, we need to know that we have two events. First, when one piece of mail is drawn at random and put aside and, second, when a second piece of mail is drawn.
These two events are dependent. If A and B are dependent events, P(A and B) = P(A) • P(B after A) where P(B after A) is the probability that B occurs after A has occurred.
So, first
- Probability of A (the first piece is letter)
- Probability of B after A
Since A already occurred and one piece of the mail was drawn (a letter), now in total we would have 9 letter and 23 total pieces
Finally, replacing in the initial formula
Finally, the probability would be 0.1630
ANSWER:
P (both are letters) = 0.1630
Answer:
The highest possible average is 348
Step-by-step explanation:
we know that
No more than 60 means -----> maximum 60 ( less than or equal to 60)
To find the possible average using proportion
Remember that the average is the number of hits in 1,000 times at bat
If the average is 300 with maximum 60 times at bat
then
The number of hits is 60*300/1,000=18 hits
If the player gets 5 hits in her next 6 times at bat
then
In 66 times at bat the number of hits is 18+5=23 hits
Find out the average
Let
