Complete question :

Anna has a box of chocolates. In the box there are milk, plain and white chocolates in the ratio 4:3:2. The box contains 72 chocolates altogether. Anna doesn't like white chocolates. Work out the probability that she will pick a chocolate that is not white?

7 / 9

Step-by-step explanation:

Calculate the number of each type of chocolate :

Milk : plain : white = 4 : 3 : 2

Total ratio = (4 +3 +2) = 9

Milk = (4/9) * 72 = 32

Plain = (3/9) * 72 = 24

White = (2/9) * 72 = 16

Probability of picking a chocolate that is not white :

Number of non-white :

(plain + milk) = (24 + 32) = 56

Probability = (required outcome / Total possible outcomes)

P(not white chocolate) = (number of non-white / total number of chocolates)

= 56 / 72

= 7 / 9

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
