At Roberta’s cafe half of her regular customers order her famous low-fat chicken sandwich. The probability of a regular customer
ordering the chicken sandwich and losing weight last month was 40%. What is the probability of someone losing weight given that they regularly ordered the sandwich?
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%.
The correct answer to this question is letter "A. complex." A number written in the form a + bi is called a complex number. The "i" part is the imaginary part of that expression, which is complex. Imaginary numbers are complex and it's hard to evaluate, sometimes.
