Answer:
Step-by-step explanation:
Looking for P(B|A)
conditional probability formula: A|B= (A∩B)/B
so B|A= (B∩A)/A
B∩A= 19+27= 46
A= 50+19+27+45= 141
46/141= .3262
NO. OF STUDENTS THAT HAVE COMPLETED BOTH SMOOTH&RYTHM=19+27=46
TOTAL NO. OF STUDENTS IN SMOOTH AND RYTHM =141
Therefore,
Probability=46/141
=0.326
do u want me to get u the answers to the whole book?
