To solve this question, use the Binomial probability formula.
The formula is given by

Where:
n = the number of trials
x = the sample we aim to try
p = the probability of success
In this question:
n = 16
x = 9
p = 0.5
Substituting in the equation:

And the combination formula:

Then:

Answer: The probability is 0.1746.
okay well usually what I would tell you would be to use the ABC method. you would multiply A (2) by C (6) to get twelve. so you need two numbers that multiply to twelve and add to -4 (the B value). but there are no numbers that fit this description so you have to use the GCF method instead
for this method you must find the GCF for all three numbers which in this case is 2. 2(x^2-2x+3) all these numbers are now prime so this is the factored form
-6+8+9=2x+3
11=2x+3
8=2x
x=4
Answer:
The time may be calculated by making the equations equal each other:
2w +7 = .5w + 10
1.5w = 3
weeks = 2
Step-by-step explanation:
C(-1,4),(1,7),(2,10) hope this helps
