Answer:
probability that at least three among four persons will take divorce = 0.343
Step-by-step explanation:
70 percent of the married persons take divorce
probability of taking Divorce = 70/100 = 7/10
probability that at least three among four persons will take divorce?
=> 3 or 4 Person will Take Divorce
P(3) = (0.7)³*0.3
P(4) = (0.7)⁴
P(3) + P(4) = (0.7)³*0.3 + (0.7)⁴ = (0.7)³ = 0.343
probability that at least three among four persons will take divorce = 0.343
