Question

HURRY

Answer 1

Here are 18 brown haired students out of 40 students 18/40=0.45
0.45 

Answer 2

Answer: 0.45

Step-by-step explanation:

From the given table, the number students have brown hair = $10+8=18$

The total number of students =$4+5+4+6+10+8+2+1=40$

Now, the probability that a student has brown hair is given by :-

$P(Br)=\frac{\text{Students with brown hair}}{\text{Total students}}\\\\\Rightarrow\ P(Br)=\frac{18}{40}=0.45$

Hence, the probability that a student has brown hair is 0.45
