Probability of the student taking neither math nor science is 35 / 150 or 0.23
<u>Explanation:</u>
<u />
Given:
Total students = 150
Number of students taking maths = 95
Number of students taking science = 75
Maths + Science = 55
Probability of student taking neither math nor science = ?
Number of students taking only science = 95 - 55
= 40
Number of students taking only maths = 75 - 55
= 20
Number of students taking neither maths nor science = 150 - 40 - 20 - 55
= 35
Probability of the student taking neither math nor science is 35 / 150 or 0.23
Answer:
Step-by-step explanation:
1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66
A = width * lengh = 23 * 10 = 230
2. width = 7
P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32
