Sagot :
Answer:
b) μ = 2 and σ = 1.29
Step-by-step explanation:
Step(i):-
Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6
Given that the probability of labelled '1'
[tex]p = \frac{1}{6}[/tex] =0.16
q = 1-p = 1- 0.16 = 0.84
Let 'X' be a random variable in binomial distribution
The mean of the binomial distribution
μ = n p
μ = [tex]12 (\frac{1}{6} ) = 2[/tex]
The mean of the binomial distribution = 2
Step(ii):-
The standard deviation of X
σ [tex]= \sqrt{npq}[/tex]
σ = [tex]\sqrt{12(0.16)(0.84}[/tex]
σ = [tex]1.269[/tex]
The standard deviation of the binomial distribution
σ = [tex]1.269[/tex]
