Answer:
Step-by-step explanation:
P(A) = Probability of a student knowing how to play guitar
= no. of students who know how to play guitar / total no. of student
= 144/200
= 0.72
P(B) = Probability of a student is left-handed
= no. of students who is left-handed / total no. of student
= 141/200
= 0.705
P(A) and P(B) are calculated to be two real numbers and do not depend on each other. So event A and B are independent.
Answer:
Step-by-step explanation:
P(A) = 144/200 = 0.72
P(B) = 141/200 = 0.705 = 0.71
The two probabilities are similar but different. From the table, a large number of students who play guitar are also left-handed: 116. So the two probabilities are NOT independent - if u are left-handed, u are more likely to play guitar n vice versa.
