Answer:
option A
2/4 = 0.5
Step-by-step explanation:
Given in the questions that,
number of student in chess club = 4
P(B) = 4/10
number of student in karate club = 6
P(A) = 6/10
number of students who are both in chess and karate club = 2
P(A∩B) = 2/10
total number of students 10
Formula to use
<h3>P(A/B) = P(A∩B) / P(B)</h3><h3> = 2/10 / 4/10</h3><h3> = 2/4</h3><h3> = 1/2</h3><h3> = 0.50</h3>
