The area of the two trianglular ends is
.. (18 cm)*(40 cm) = 720 cm²

The perimeter of the triangular end is
.. 2*41 cm +18 cm = 100 cm
so the lateral area is
.. (100 cm)*(46 cm) = 4600 cm²

The total surface area is the sum of the end area and the lateral area.
.. 720 cm² +4600 cm² = 5320 cm²

What is the probability of selecting a red card from a standard deck of 52 playing cardships that does not contain a joker?

Rasek [7]

We know that the deck of cards contain half red and half black cards or you can say we have 26 red cards and 26 black cards.
we have to find probability of red cards from a deck of cards
so,
probability (selecting red card) = $\frac{26}{52}$
= $\frac{1}{2}$

Probability ( selecting red card ) = <span> $\frac{1}{2}$ Answer</span>
