Suppose that four microchips in a production run of fifty are defective. A sample of six is to be selected to be checked for defects. (a) How many different samples can be chosen? (b) How many samples will contain at least one defective chip? (c) What is the probability (as a percent) that a randomly chosen sample of six contains at least one defective chip? (Round your answer to one decimal place.) %

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

here is your mark brainliest

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
