How do you enlarge something by a ratio?
Say you want to enlarge a triangle 3x its original size. You would take all of the sides and multiply the original lengths by 3. If it is a triangular prism, don't forget to multiply the third dimension by 3 as well.
What is the probability of drawing 3 cards that are all 6 from a deck of cards?
The probability of drawing 3 sixes from a deck of 52 cards is (4 in 52) times (3 in 51) times (2 in 50) which is (24 in 132600) or (1 in 5525) or about 0.0001810.
What is the probability of drawing 3 cards that are all face cards?
The probability of drawing the first face card is 12 in 52. The probability of drawing the second is 11 in 51. The probability of drawing the third is 10 in 50. Thus, the probability of drawing three face cards is (12 in 52) times (11 in 51) times (10 in 50) or (1320 in 132600) or about 0.009955.
What is the probability of drawing a 2 3 or 4 from a normal deck of cards?
The probability of drawing a 2, 3, or 4 from a standard deck of 52 cards is (3 times 4) in 52, or 12 in 52, or 2 in 13, or about 0.1538.
What will the height of the actual bookshelf be if the scale of the drawing is 1 cm equals 2 ft?
It would depend on the size of the drawing. If it's drawing height is 2 cm, the actual height would be 2*2ft = 4 ft tall. If the drawing height was 3 cm, the actual height would be 3*2ft = 6 ft tall.
