Question

Probability - I am struggling to find which sections/numbers to use in order to solve this section of the question. I will give brainliest to anyone who can help figure it out

Answer 1

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

Answer 2

Step-by-step explanation:

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
