percents are: 

	     1 year     2 years     3 years

Male           0.67        0.45        0.20
Female         0.73        0.64        0.39


there are 200 males and there are 300 females.

.67 * 200 = 134 males who stayed at least one year.
.73 * 300 = 219 females who stayed at least one year.

total is 353 out of 500 employees who stayed as least 1 year.

353 / 500 = .706

the probability that an employee stayed at least one year is therefore equal to .706.
