Answer:
a. 0.349
b. 0.651
c. 0.93
Step-by-step explanation:
According to the Question,
- Given, About 10% of all adults deliberately do a one-time fling and In a group of ten adult friends.
Thus, p=0.10 , n=10 &
Now, Use Binomial distribution =
a. p(x=0) ⇒ = 0.349
Thus, The Probability that No one has done a one-time fling = 0.349
b. p(x≥1) = 1 - p(x=0) ⇒ 1 - 0.349 = 0.651
Thus, The Probability that at least one person has done a one-time fling = 0.651
c. p(x≤2) = p(x=0) + p(x=1) + p(x=2)
p(x≤2) = +
+
on Solving, we get
p(x≤2) = 0.349 + 0.347 + 0.194
p(x≤2) = 0.93
Thus, The Probability that No More Than two person have done a one-time fling = 0.93
