Whitepunk [10]

Answer: \mu=2.88\ \&\ \sigma^2=0.115

Step-by-step explanation:

Given : The probability of a correct classification of any part is : p=0.96

sample size : n= 3

The formula to find the mean and variance for binomial distribution is given by :-

\mu=np\\\\\sigma^2=np(1-p)

Let the random variable X denote the number of parts that are correctly classified.

The, for the given situation, we have

\mu=3(0.96)=2.88\\\\\sigma^2=(3)(0.96)(1-0.96)=0.1152\approx0.115

Hence, the mean and variance of X are 2.88 and 0.115 respectively.

Express 20% as a fraction in its lowest form? Thanks

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ 20% as as a fraction in lowest terms is \frac{1}{5}

Percents are out of 100% so write 20% out of 100% as a fraction:

\frac{20}{100}

Both the numerator and denominator can be divided by 20 so once divided, you get \frac{1}{5}
