There are 15 boys in a class with 14 girls. find the probability of selecting a girl then a boy

A 48 percent chance. If you need help here is what you do, first you add up the two units which in this case is 15 boys and 14 girls which makes 29 girls then you divide the unit you would like to find the probability of which is girls and now the equation should look like so 14/29 then you divide and get 0.4827
but percentages are the two numbers after the 0 so you see if you need to round it and you get 48 percent or if you want it as a fraction its 14/29.

31 is prime. and it’s prime factorization is just 31.
