Question

HURRY

The table shows the number of boys and girls that have black, blonde, brown, or red hair color.
What is the probability that a student has brown hair? ( round to the nearest hundredth)

Black~ (boys)- 4 ( girls)- 5
Blonde~ (boys)- 4 (girls)- 6
Brown~ (boys)- 10 (girls)- 8
Red~ (boys)- 2 (girls)- 1

Answer 1

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

Answer 2

Answer: 0.45

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)=(18)/(40)=0.45`

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