It depends on what their general health is, their diet, their history of longevity.If they are in good health the odds are quite good, but if they eat poorly, perhaps smoke, have great amounts of stress or have a long history of family illness the odd they'll reach 9 decades decrease.
90 out of 100
The odds of living past 90 vary based on factors such as genetics, lifestyle, and healthcare access. Generally, about 30% of people who reach age 65 will live to 90, but this percentage can be higher for those with healthier lifestyles and lower for those with chronic health issues. Women typically have a higher likelihood of reaching this age compared to men. Additionally, advancements in medicine and public health may further increase these odds over time.
A mother's odds of producing twins depend on several factors, including genetics, age, and ethnicity. Generally, the natural occurrence of twins is about 1 in 90 pregnancies. Women over 30 and those with a family history of twins, especially fraternal twins, have higher chances. Additionally, fertility treatments can significantly increase the likelihood of having twins.

Suppose that in a sample of 100 men, 90 have drunk wine in the previous week, while in a sample of 100 women only 20 have drunk wine in the same period. The odds of a man drinking wine are 90 to 10, or 9:1, while the odds of a woman drinking wine are only 20 to 80, or 1:4 = 0.25:1. The odds ratio is thus 9/0.25, or 36, showing that men are much more likely to drink wine than women. The above example also shows how odds ratios are sometimes sensitive in stating relative positions: in this sample men are 90/20 = 4.5 times more likely to have drunk wine than women, but have 36 times the odds. The logarithm of the odds ratio, the difference of the logits of the probabilities, tempers this effect, and also makes the measure symmetric with respect to the ordering of groups. For example, using natural logarithms, an odds ratio of 36/1 maps to 3.584, and an odds ratio of 1/36 maps to −3.584.
