The complete question is
Drew has 4 times as many baseball cards as Mark. Katie has 3 fewer than than half as many cards as Mark. In all they have 162 baseball cards. How many does each have?
Solution -
Let the number of cards with Mark be "X"
Number of cards with Drew = 4 *X = 4X
Number of Cards with Katies = 0.5 X -3
Sum of all the cards is equal to 162
X+4X + 0.5 X -3 = 162
5.5 X = 165
X = 30
Cards with Mark = 30
Cards with Drew = 4 * 30 = 120
Cards with Katei = 15-3 = 12

Answer:
1150
Step-by-step explanation:
question one
1, 2, 3, 4, 5, 6
question two
3/6 or 1/2
question three
3/6 or 1/2
question four
2/6 or 1/3
question five
4/6 or 2/3
you use the list from question one, and count how many fit the criteria and put that number over the total ( which is 6 in this case )
Relative frequency = (number of times an item appears) /(TOTAL numbers)
Relative frequency (selecting Red ) = 13/30 =0.434
