sladkih [1.3K]

Answer:

1/2 ; 1/4

Step-by-step explanation:

Number of cards in a deck = 52

Number of red cards = 26

Number of spades = 13

Probability of event A :

P(A) = required outcome / Total possible outcomes

P( red card) = number of red cards / total cards in deck

P(red card) = 26 / 52 = 1/2

P(spade) = number of spades / total cards in deck

P(red card) = 13 / 52 = 1 / 4

Can someone help me with my last homework question, please show the work and explain what you did so I can understand! if you do

ruslelena [56]

Ok, so I worked out the problem.

So for part a) you just multiply 8 by 25% then add the product to get the new perimeter.

Part B you Add all sides for the original square and the new square to get the perimeters of each then you divide the old square perimeter by the new square perimeter to get the percentage.

Part C you get the areas pf bother squares then divide the old square area by the new square area to get the percentage change.

If you have any questions, let me know.
