Answer:
a) Red marble: 6/17
b) Green marble: 11/17
c) Purple marble : 0/17 = 0
d) a red or a green marble: 1
Step-by-step explanation:
Number of marbles: 17
Probability to pick one red marble: (# successes) / (# total) = 6/17
Probability to pick a green marble: (# successes) / (# total) = 11/17
Probability to pick a purple marble: (# successes) / (# total) = 0/17 = 0
Probability to pick a green marble or a red marble: Prob one green + prob one red = 11/17 + 6/17 = 17/17 = 1
Answer:3.38
Step-by-step explanation:
Count, N: 5
Sum, Σx: 18
Mean, μ: 3.6
Variance, σ2: 11.44
Steps
(10 - 3.6)2 + ... + (2 - 3.6)2
5
=
57.2
5
= 11.44
σ = √11.44
= 3.38
X^-3
Anything to the power of 0 is 1 so
X^-3/1= X^-3
