Question

A farm has 5 brown cows and 10 white cows. A fence is open and a cow escapes. What is the probobility that it will be a brown cow? A. 50%B.1/2C.33%D.20%

Answer 1

A farm has 5 brown cows and 10 white cows

Total of cows:

`5+10=15`

Probability is represented by:

`P=\frac{NU\text{MBER OF FAVOURABLE OUTCOMES}}{\text{TOTAL NUMBER OF FAVOURABLE OUTCOMES}}`

So, the probability of a brown cow escapes:

`\begin{gathered} P=(5)/(15)=0.33\text{ (decimal form)} \\ P=0.33\cdot100=33\text{ percent} \end{gathered}`
