Explanation / Answer

for this exercise we just need the information of the table

a)

man and is in favor of a 4 day work week = 300

total = 6000

Probability = 300/6000 = 0.05

b)

employee is female = 4200

total = 6000

probability = 4200 / 6000 = 0.7

c)

she is in favor of flexible hours = 2100

is female = 4200

probability = 2100 / 4200 = 0.50

d)

in favor of 5 day work week = 2700

total = 6000

probability = 2700 / 6000 = 0.45 = 45%

e)

female and flexible = 2100

flexible = 2400

probability = 2100 / 2400 = 0.875

f)

male and in favor of 5 day work = 1200

total = 6000

probability = 1200 / 6000 = 0.2 = 20%
