So you foil out the problem and get
no because you are not distributing numbers that multiply with each other and form new expressions
Simplify to -30-35y=-30-5y
Move all ys to the right and move constants left, -30y= 0
Divide by -30
y=0
Answer:
0.2700
Step-by-step explanation:
-Notice that this is a binomial distribution with p=0.52, n=4 and x=3.
-The formula for the binomial probabilities is given as:

The probability than in 4, exactly 3 order their food on the go is:

Hence, the probability that exactly 3 order their food on the go is 0.2700
