Answer:
The probability that 12 people in your sample are carrying no cash is 0.0712
Step-by-step explanation:
n = 100
p(no cash) = 0.09
x = 12
By applying binomial distribution
P(x,n) = nCx*px*(1-p)(n-x)
P(x = 12) = 0.074.
The probability that 12 people in your sample are carrying no cash is 0.074.
n = 100
p(less than 50) = 0.78
x = 75
By applying binomial distribution
P(x,n) = nCx*px*(1-p)(n-x)
P(x = 75) = 0.0712
The probability that 12 people in your sample are carrying no cash is 0.0712

Answer:
Step-by-step explanation:
Given
Required
is calculated as:
Since it is a probability with replacement, we have:
For x > 1, we have:
For x < 2, we have:
becomes
When 2 or more expressions are equivalent, that means they have the same outcome or result.
–10 = –6 + 2c
+ 6 + 6 Add 6 to cancel out -6
-4 = 2c
/2 /2 Divide by 2 to get c variable alone
-2 = c Choice C is the correct answer
