In Canada, 226 440 men aged 65-74 have the medical condition tinnitus (ringing or swooshing sounds in the ears). If the male population in Canada aged 65 years and over is 1 887 000, what is the probability that a man aged 65 years or older will have tinnitus? Express your answer as a decimal rounded to nearest hundredth and a percentage rounded to nearest whole number.
To find the probability that a man aged 65 years or older will have tinnitus, we divide the number of men aged 65-74 with tinnitus (226 440) by the total male population aged 65 years and over (1 887 000).
Probability = 226440 / 1887000 ≈ 0.1200
As a decimal rounded to the nearest hundredth: 0.12
As a percentage rounded to the nearest whole number: 12%
