 <translate> Probability of getting red ball from bag1 and then red from bag 2 = 3/5*5/10 = 15/50
Probability of getting black ball from bag1 and then red from bag 2 = 2/5*4/10 = 8/50
Now comes the condition, hence apply conditional probability:
P(Red)/ P(Red + Black)
(15/50)/(15/50+8/50) = 15/50 /23/50 = 15/23.
Thus, the answer is (E). <yor> Ó ṣeé ṣe kó jẹ́ pé bọ́ọ̀lù aláwọ̀ pupa ni bọ́ọ̀lù 1 àti bọ́ọ̀lù aláwọ̀ pupa ni bọ́ọ̀lù 2 = 3/5*5/10 = 15/50 Ó ṣeé ṣe kó jẹ́ pé bọ́ọ̀lù dúdú ló wà nínú àpò 1 àti bọ́ọ̀lù pupa tó wà nínú àpò 2 = 2/5*4/10 = 8/50 Ní báyìí, a máa rí ipò, nítorí náà, a máa lo ìdánilójú tó bá ipò mu: P ((Red) / P ((Red + Black) (15/50)/(15/50+8/50) = 15/50 /23/50 = 15/23.
