Problem is, Black people make up about 14% of the total population. LGBT people make up at most 2%. So the odds are way lower.
The problem is (this can go on forever ...) that nobody knows exactly how many people are LGBT since there are many people who will never admit that they are LGBT, even to themselves.
Williams Institute says that a little less than 4% of the U.S. population self-identify as LGBT, and less than 10% have said that they ever had a same-sex encounter or have felt any attraction to the same sex.
