Answer:
<u>84 students </u>
Step-by-step explanation:
See the attached table
As shown there are 20 students from Math club, 7 of them would like to choose calculators.
so, the probability of students who choose calculators = 7/20
If there are 240 students in the Math club
So, the number of students expected to choose calculators = 240 * 7/20
<u>So, the number of students = 84 students </u>
