Answer:
Step-by-step explanation:
cheese With toppings Total
No of pizzas sold 24 16 40
Eaten at work 12 10 22
Not eaten at work 12 6 18
a) Prob for a cheese pizza eaten at work=[tex]\frac{12}{40} =0.30[/tex]
b) Prob a pizza with either one or more toppings, and it was not eaten at work.=[tex]\frac{6}{40} =0.15[/tex]
c) Prob for a cheese pizza, or it was a pizza eaten at work.=P(cheese)+P(pizza eaten at work)-P(both)
= [tex]\frac{24}{40} +\frac{22}{40} -\frac{12}{40} \\=\frac{34}{40} \\=0.85[/tex]
The probability of cheese pizza eaten, pizza with either one or more toppings and it was not eaten, and cheese pizza or it was a pizza eaten are 0.30, 0.15, and 0.85 respectively.
What is probability?
Probability means possibility. It deals with the occurrence of a random event. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
According to the condition, the table is shown.
Cheese With toppings Total
No. of pizza sold 24 16 40
Eaten at work 12 10 22
Not eaten at work 12 6 18
a. Probability for cheese pizza eaten at work will be
[tex]\rm Probability = \dfrac{12}{40} = 0.30[/tex]
b. Probability of a pizza with either one or more toppings and it was not eaten at work will be
[tex]\rm Probability = \dfrac{6}{40} = 0.15[/tex]
c. Probability for a cheese pizza or it was a pizza eaten at work will be
[tex]\rm Probability = P(cheese) + P(eaten \ at \ work) - P ( both) \\\\\rm Probability = \dfrac{24}{40} + \dfrac{22}{40} - \dfrac{12}{40}\\\\\rm Probability = 0.85[/tex]
