A company that manufactures computer components has a 3% defective rate. If 10 components are randomly selected, find the probability of getting 2 defective components. Binomial Probability Formula: P(x) = nCx px qn-x

The probability of getting 2 defective items

P(X=2) = 0.0317416

Step-by-step explanation:

Step(i):-

Given that size of the components n = 10

Given that the probability of getting the defective item

           p = 3% = 0.03

           q = 1-p =1- 0.03 = 0.97

Let 'X' be a random variable in a binomial distribution

Step(ii):-

The probability of getting 2 defective items

P(X =2) = 45 × 0.000705

P(X=2) = 0.0317416

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
