Number of customers = 300
Number of customers that are male and has an open-toe shoes = 11
P(male and open-toe) = 11/300
Number of customers that are male = 139 + 11 = 150
Number of customers that are male and has an open-toe shoes = 11
Given that the customer is male,
P(open-toe) = 11/150
No, the two probabilities are not the same. The first probability has 2 variables - the gender and the shoe-type. The second probability has only 1 variable - the shoe-type

Answer:
1/4 ; $28.25
Step-by-step explanation:
Given the following :
Cost of stationeries:
Pencil:$1.20
Eraser:$1
Ruler:$0.50
Total : $169.50
Let total Stationeries purchased = t
Fraction of pencils = 1/3t
Remainder = t - 1/3 = 2/3t
Fraction of eraser = 5/8 of remainder
Thus ;
Fraction of eraser = 5/8 * (2/3)t= 10/24 = (5/12)t
Rest were ruler ;
(2/3)t - (5/12)t= (8 - 5)/12
= 3 / 12 = 1/4t
Fraction of rulers = 1/4
Amount spent on erasers:
(5/12) of the total cost of stationery
(5/12) * 169.50 = $70.625
B.) How much more did she spend on erasers than rulers
Amount spent on rulers :
(1/4) * $169.50 = $42.375
Take the difference :
$(70.625 - 42.375) = $28.25
