Clara writes the following proof for the theorem:if the diagonals of a quadrilateral bisect each other

tekilochka [14]

well, for a square the diagonals do bisec each other, they cut each other in two equal halves.

and for a rectangle, they do as well, mind that a square is a rectangle with all equal sides anyway.

wait just a second, for a parallelogram, they do bisect as well.

hold the mayo, for a rhombus they do too, what the dickens is going on?

well, what do they all those have in common?

they're all quadrilaterals, but, they all have two pairs of parallel sides.

mind you that, a kite is also a quadrilateral, however, it doesn't have all equal sides and the diagonals do not bisect each other, and yes, it has no pairs of parallel sides.

You have 1 blue suit, 2 black suits, and 1 brown suit, You also have 2 blue ties, 3 red ties, and 3 pink ties. What is the proba

tia_tia [17]

The probability that you pick a striped shirt AND a blue suit is 1/4 AND a pink tie is 3/8.

According to the statement

Number of blue suit = 1

Number of black suit = 2

Number of brown suit = 1

Number of blue ties = 2

Number of red ties = 3

Number of pink ties = 3

Now we find the probability by its formula

Probability that picked suit is blue = blue suits/ total number of suits

Probability = 1/4

Now,

Probability that picked tie is pink = Pink tie / total number of ties

Probability = 3/8

So, The probability that you pick a striped shirt AND a blue suit is 1/4 AND a pink tie is 3/8.
