At a competition with 8 runners, 2 medals are awarded for first and second
Dafna1 [17]

Answer: Option 'A' is correct.

Step-by-step explanation :

Since we have given that

Number of medals = 2

Number of runners = 8

We need to find the number of ways to award the medals.

We would use "fundamental theorem of counting" to find the number of ways.

So, number of ways is given by

8 × 7 = 56

Hence, option 'A' is correct.

Salsk061 [2.6K]

Answer:

\sf \dfrac{203}{4108}

As a decimal = 0.05 (nearest hundredth)

Step-by-step explanation:

\sf Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ possible \ outcomes}

First pick:

\sf \implies P(pink)=\dfrac{30}{80}

As the case is NOT replaced, second pick:

\sf \implies P(pink)=\dfrac{30-1}{80-1}=\dfrac{29}{79}

As the case is NOT replaced, third pick:

\sf \implies P(pink)=\dfrac{29-1}{79-1}=\dfrac{28}{78}

Therefore,

\sf \implies P(pink \ and \ pink \ and \ pink)=\dfrac{30}{80} \times \dfrac{29}{79} \times \dfrac{28}{78}=\dfrac{203}{4108}

Answer as a decimal = 0.05 (nearest hundredth)
