Answer:
The required probability is approximately 0.3467.
Step-by-step explanation:
Let X represents the event of making an online purchase,
Given,
The probability of making an online purchase, p = 0.35,
While, the probability of not making the online purchase, q = 1 - p = 0.65,
Hence, by the binomial distribution formula,
Where,
Hence, the probability that at most 3 of them has made an online purchase is,
P(x ≤ 3) =P(x=0) + P(X=1) + P(X=2) + P(x=3)
