(Simplify your answer. Do not round.) Answer by ikleyn(52894) (Show Source):
The space event consists of 4 elements
BB, BG, GB, GG
each with the probability .
The favorable events are BB, BG and GB.
Therefore, the probability under the problem's question is = 0.75 = 75%. ANSWER
Solved, answered and carefully explained.
