Answer:

Explanation:

To calculate, the binomial distribution  formula can be applied

P(X)= nCx * Px * (1 - P)^(n - x)

Random sample of 6 adults:

P(X≥3) = P(X=3) + P(X=4) + P(X=5) + P(X=6)

(6 C 3​)0.30^3 * 0.7(6-3) + (6 C 4​)0.30^4* 0.7^(6-4) +(6 C 5​)0.30^5* 0.7^(6-5) + (6 C 6)0.30^6* 0.7^(6-6) =

0.1852+0.0595+0.0102+0.0007

= 0.2556

[6 C 3 = 6!/(6-3)!3! = 1*2*3*4*5*6/1*2*3*1*2*3, and to calculate others apply to this formula]
