The age at which men in United States marry for the first time follows the normal distribution with a mean μ = 26.8 years with the standard deviation of the distribution o= 4.5 years. If one married man is selected at random, find the probability that the age at which he married for the first time was less than 25, P(x < 25) O 0.3446 0.7323 O 0.4494 O 0.4681 Câu hỏi 19 find the probability that the age at which he married for the first time was between 22 and 30, P( 22 < x < 30) O 0.4495 O 0.7329 O 0.6184 3 điểm O 0.3441
