Answer:
0.0818.
Step-by-step explanation:
This question can be solved using the binomial theorem because the probability of success is fixed.
Total adults = n = 20
Required attempts = r = 12
Probability of success = p = 3/4 = 0.46
Binomial Theorem formula:
P(X=r) = nCr * p^r * (1-p)^(n-r).
Substituting the values:
P(X=12) = 20C12 * 0.46^12 * (1-0.46)^8
P(X=12) = 125970 * 0.46^12 * (0.54)^8 = 0.0818 (to the nearest 3 significant figures).
So the probability that exactly 12 people use their smart phones in meetings or classes out of 20 is 0.0818!!!
Answer:
18
Step-by-step explanation:
f(x)=2x(2+1)
f(3)=2(3)(2+1)
=6(2+1)
=12+6
=18
