n = no of trials = no of students surveyed =12
Required probability = prob atmost 4 students take chemistry
=
Substituting we get the cumulative probability
as
0.4382
round off to 0.438
Option b is correct answer
There are 3 girls & 4 boys.
Each student makes 8 paper airplanes.
Amount of paper airplanes created by girls: 3 x 8 = 24
Amount of paper airplanes created by boys: 4 x 8 = 32
