Answer: B
Step-by-step explanation:
A factorial is multiplying the integer and all of the integers below it together.
Use binomial distribution, with p=0.20, n=20, x=3
P(X=x)=C(n,x)p^x (1-p)^(n-x)
P(X>=3)
=1-(P(X=0)+P(X=1)+P(X=2))
=1-(C(20,0)0.2^0 (0.8)^(20-0)+C(20,1)0.2^1 (0.8)^(20-1)+C(20,2)0.2^2 (0.8)^(20-2))
=1-(0.0115292+0.057646+0.136909)
=1-0.206085
=0.793915
1300+22=1322 1322+6=1328 answer: 1328
She will use 13 there are four 1/4 per cup 4 times 3 plus 1 =13
To get the store from which there's a likelihood of paying $18.75 for a pair shoes we consider the median of the data sets, which can represent the center of the measure of dispersion. This gives us store as the most likely store among the stores given from which you'll pay the stated price. This is because it's median is approximately $19.5
