Question

What is the probability it lands between birds B and C?

Answer 1

B. 1/9

Step-by-step explanation

The probability of an event is the number of favorable outcomes divided by the total number of outcomes.

`P(A)=\frac{favorable\text{ outcomes}}{\text{total outcomes}}`

Step 1

Let A represents the event that the birds lands between b and c

a)so, in this case the favorable outcome is that the birds lands between b and c, the length bewtween b and c is

`BC=2\text{ in}`

and , the total outcome is the total lengt, so total outcome = AD

`\begin{gathered} AD=10\text{ in+ 2 in +6 in} \\ AD=18\text{ in} \end{gathered}`

b) now,replace in the formula

`\begin{gathered} P(A)=\frac{favorable\text{ outcomes}}{\text{total outcomes}} \\ P(A)=\frac{2i\text{n }}{18\text{ in}}=(1)/(9) \\ P(A)=(1)/(9) \end{gathered}`

therefore, the answer is

B. 1/9
