A) \[0.22\]
B) \[0.11\]
C) \[0.33\]
D) \[0.44\]
Correct Answer: C
Solution :
[c] Let W: Player wins on Monday F: Track is fast S: Track is slow We are given that \[P(F)=0.7,\] \[P(S)=0.3,\] \[P(W/F)=0.3,\] \[P(W/F)=0.3,\]\[P(W/S)=0.4\] \[\therefore \,\,\,\,P(W)=P(W\cap F)+P(W\cap S)\] \[=P(F)\times P(W/F)+P(S)\times P(W/S)\] \[=0.7\times 0.3+0.3\times 0.4=0.33\]You need to login to perform this action.
