Answer:
b) μ = 2 and σ = 1.29
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6</em>
<em>Given that the probability of labelled '1'</em>
<em> </em> =0.16
<em> q = 1-p = 1- 0.16 = 0.84</em>
Let 'X' be a random variable in binomial distribution
The mean of the binomial distribution
μ = n p
μ =
<em>The mean of the binomial distribution = 2</em>
<u><em>Step(ii):-</em></u>
The standard deviation of X
σ
σ =
σ =
<em>The standard deviation of the binomial distribution</em>
<em> </em> σ =
