What is the probability of getting an A in College Algebra and getting a 30 on the ACT test? 0.09 0.90 0.44 0.25 A single card is drawn from a deck. What is the probability of selecting a queen or a heart? 17/52 4/13 15/52 9/26 The probability that John and Sue go to the movies is 0.35. The probability that Sue goes to the movies is 0.5. What is the probability that John goes to the movies given that Sue goes? 0.7 0.175 0.15 0.85Explanation / Answer
P( A in college Algebra )=0.2
P(got A in college Algebra given that person got 30 in ACT)=P( A in college Algebra and getting 30 in ACT)/P( getting 30 on ACT )
Thus, P( A in college Algebra and getting 30 in ACT)=0.2*0.45 =0.9 answer B
