John concludes that the probability of drawing a dime from a jar containing 40 dimes and 40 nickles is 0.5. which experiment justifies johns conclusion?

John assumed that out of 80 coins contained in the Jar, 40 coin pieces is a dime, which makes 40 out of 80 equal to 0.5. But this assumption is wrong as for each draw you'd only have 1/80 chance of getting a dime combining and giving both types of coin each a chance to be drawn.

- My answer -

The properties of the parallelogram are simply those things that are true about it. These properties concern its sides, angles, and diagonals.

The parallelogram has the following properties:

Opposite sides are parallel by definition. Opposite sides are congruent. Opposite angles are congruent. Consecutive angles are supplementary. The diagonals bisect each other.

If you just look at a parallelogram, the things that look true (namely, the things on this list) are true and are thus properties, and the things that don’t look like they’re true aren’t properties.

And if you need anything else on I am happy to help okay.
