Answer:
The probability of losing weigth given that the sandwich was ordered is 80%.
Step-by-step explanation:
The probability of a regular costumer ordering the sandwich is said to be 50% and the probability of someone ordering that sandwich and losing weight is 40%. So we the probability of someone losing weigth if the sandwich was ordered is:
sandwich and losing weigh = (ordering sandwich)*losing weigth
losing weigth = (sandwich and losing weigth)/(ordeing sandwich)
losing wiegh = 40%/0.5 = 80%
The probability of losing weigth given that the sandwich was ordered is 80%.
Let the numbers be x and y.
by the first statement of the question, we get , x + y = 30.,,..(1)
by the second satement, we get , x = y+ y => x=2y... (2)
from equation (2), let us put the value of x in equation (1),
x + y = 30
=> 2y + y = 30
=> 3y = 30
=> y =30/3
=> y = 10
and x=2y => x = 2*10 = 20
in short, the numbers are 10 and 20
