Answer:
0.336 or 33.6%
Step-by-step explanation:
It follows from the question that the probability of a complaint is 35% = 35/100 = 0.35. Let's call this probability, p.
The probability of no complaint is mutually exclusive of p since both are complements. Let's call this q. Then
q = 1 - p = 1 - 0.35 = 0.65
The distribution is a binomial distribution.
Events of each call are independent.
The probability of 2 calls with complaint out of 5 is

Answer:
x= 1/3
y = -8
Step-by-step explanation:
-2y+ y = 8 equation 1
-3x -y =7 equation 2
using equation 1 we have:
-2y+ y = 8
-y = 8
y = -8 equation 3
using equation 3 in equation 2 we have:
-3x -y=7
-3x -(-8)=7
-3x +8 =7
-3x = 7-8
-3x = -1
x= 1/3
