Poly is working on the probabilities of each food option being selected in her card game. remember, a standard deck of 52 playing cards contains 4 suits (hearts, diamonds, clubs, and spades), and each suit contains 13 cards, labeled 2 through 10, as well as jack, queen, king, and ace. hearts and diamonds are red, and spades and clubs are black. the face cards are jacks, queens, and kings.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
