The probability that at least one client will disclose a food allergy will be 0.6323 when the percentage of customers who will disclose a food allergy is 0.08.
Given that.
The percentage of customers who will disclose a food allergy is 0.08
At Ying Ying's bakery, 121 people place orders on a single day.
We can utilize the binomial distribution if we believe that each of the 12 clients has an equal probability of reporting a food allergy.
Formula for Binomial probability distribution:
P(X=x)=ⁿCₓpˣ(1-p)ⁿ⁻ˣ
Where P(x)= probability of getting success in x trials,
n= sample size ,
p represents the probability that each event will succeed.
As stated, we have n=12
p=0.08
Let x signify that the client will disclose a food allergy.
Following that, the probability that at least one client will disclose a food allergy will be:
P(x≥1)=1-P(x<1)
=1-P(x=0)
=1-¹²C₀(0.08)⁰(1-0.08)¹²⁻⁰
=1-(1)(0.12)¹²
=1-0.3677
=0.6323
Therefore, the probability that at least one client will disclose a food allergy will be 0.6323 when the percentage of customers who will disclose a food allergy is 0.08.
