A jar contains 7 poker chips: 3 blue, 3 red and 1 white. You randomly select two chips from the jar. What is the probability that your selection includes the white chip? Round your answer to two decimal places.

The probability that you will have a white chip is 0.309

Step-by-step explanation:

You on the first try have a 1/7 or 14.285% chance the second one has a 1/6 or a 16.666% you then add them together and you have a 30.9% chance

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

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
