suppose 50 percent of the customers at pizza palooza order a square pizza, 72 percent order a soft drink, and 36 percent order both a square pizza and a soft drink. is ordering a soft drink independent of ordering a square pizza?

Respuesta :

No, ordering a soft drink is not independent of ordering a pizza

An independent event is one that is unrelated to the likelihood of another event occurring (or not happening). In other words, the occurrence has no bearing on the likelihood that a subsequent event will also occur.

P (square pizza is ordered) = 50% or 0.5

P (Soft drink is ordered) = 72% or 0.72

P ( squared pizza and soft drink are ordered) = 36 % or 0.36

Computing independency:

Ordering pizza and ordering a soft drink will be independent if:

P (squared pizza) + P (soft drink) = 1

0.5 + 0.72 ≠1

1.22≠1

Therefore, ordering pizza and ordering a soft drink is not independent
