Rodrigo is buying snacks for a party he bought 2 1/5 pounds of mixed nuts

She spends about 12.45 on the nuts.

Step-by-step explanation:

2/3(7.50)+1/2(2.40)+1 1/4(5.00)

4.75

Step-by-step explanation:

2 1/5= 11/5= 2.2 pounds

10.45 / 2.2 = $4.75

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
