How many ways are there to select a 5-card hand from a regular deck such that the hand contains at least one card from each suit
Snezhnost [94]

Answer:

There are 685464 ways of selecting the 5-card hand

Step-by-step explanation:

Since the hand has 5 cards and there should be at least 1 card for each suit, then there should be 3 suits that appear once in the hand, and one suit that apperas twice.

In order to create a possible hand, first we select the suit that will appear twice. There are 4 possibilities for this. For that suit, we select the 2 cards that appear with the respective suit. Since there are 13 cards for each suit, then we have {13 \choose 2} = 78 possibilities. Then we pick one card of all remaining 3 suits. We have 13 ways to pick a card in each case.

This gives us a total of 4*78*13³ = 685464 possibilities to select the hand.

The base of the right prism is a rhombus with the side 7 cm. The altitude of the prism is h=13 cm. Find the lateral area of the
Art [367]

Answer:The lateral area is 364\ cm^{2}

Step-by-step explanation:

we know that

The lateral area of the right prism is equal to

LA=Ph

where

P is the perimeter of the base

H is the height of the prism

Find the perimeter of the base P

P=4(7)=28\ cm ----> the rhombus has  four equal sides

h=13\ cm

substitute

LA=28(13)=364\ cm^{2}
