Posterior probability of no heart disease

In an ethnic group, $30\%$ of the adult male population is known to have heart disease. A test indicates high cholesterol level in $80\%$ of adult males with heart disease. But the test also indicates high cholesterol levels in $10\%$ of the adult males with no heart disease. Then the probability (round off to 2 decimal places), that a randomly selected adult male from this population does not have heart disease given that the test indicates high cholesterol level, equals __________
