Answer: The probability of picking 7 and then picking a number greater than 7 is
or 0.3
Step-by-step explanation: Probability
Probability shows us the chances of an event occurring.
Now, given that we have already picked three cards. therefore, 7, 8, and 9.
The number of possible outcomes is 3.
the probability of card 7,
Now, as card seven is already picked up cards 8 and 9 are the only card left.
therefore, the sample size(possible outcomes) was reduced to 2 only.
Also, cards 8 and 9 both are greater than 7, thus the desired outcome is also 2.
Further the probability of the number greater than 7 occurring,
Probability picking a number greater than 7
The probability of picking a 7 and then picking a number greater than 7
= Probability of card 7 occurring x probability of card 8 and 9 occurring.
You're welcome. Pls give me brainiest
Answer:
0.0183
Step-by-step explanation:
The percentage of students, who received their DTaP vaccine is 95%.
This implies that:

and

The standard deviation of the proportion is


We want to find the probability, that the sample proportion,


X+y=56
7x-12=3y
7x-3y=12
3x+3y=168
7x-3y=12
10x=180
X=18
56-18=y
Y=38
Answer:

Step-by-step explanation:
The expression given can be rewritten as:
Because +(-n) is just -n. Then, combine like terms to get:

Substitute
for x to get:

Which can be rewritten as:

Which is:
.
as a mixed number
Hope this helps :)
