Answer: 0.77
Step-by-step explanation:
Given : Probability that a student chooses a turkey sandwich is
P(Turkey )= 0.10
Probability that a student chooses an egg salad sandwich is
P(egg salad)=0.67
Also, it is impossible for a student have both lunches.
∴ P(Turkey and egg salad) =0
Now , the probability that a student chooses a turkey or egg salad sandwich will be
P(Turkey or egg salad) = P(Turkey )+ P(egg salad)- P(Turkey and egg salad)
= 0.10+ 0.67-0 = 0.77
Hence, the probability that a student chooses a turkey or egg salad sandwich= 0.77
