The probability that a student buys coffee OR a muffin before class is 55%
<h3>How to determine the probability?</h3>
The given parameters are:
P(Coffee) = 30%
P(Muffin) = 40%
P(Tea) = 20%
P(Coffee and Muffin) = 15%
P(Tea and Muffin) = 10%
The probability that a student buys coffee OR a muffin before class is
P(Coffee or Muffin) = P(Coffee) + P(Muffin) - P(Coffee and Muffin)
This gives
P(Coffee or Muffin) = 30% + 40% - 15%
Evaluate
P(Coffee or Muffin) = 55%
Hence, the probability that a student buys coffee OR a muffin before class is 55%
