Explanation / Answer
Answer to the question is as follows:
a. P( selecting red bean) = 15/(15+12+8+10+13+7) = .2308
b, P( black or purople ) = (8+7)/(15+12+8+10+13+7) = .2308
c. P( green and an orange with replacement) = (12/65) * (11/65) = .0312
d. P( green and an orange with replacement) = (12/65) * (11/64) = .0317
e. P( 2 reds without replacement) = (15/65)*(14/64) = .0505
