Question

(PLEASE HELP, 100 POINTS!) A young boy has a penny, a nickel, a dime, a quarter, and a half-dollar coin. He puts all the coins in his hand and tells his friend that he can randomly choose two of the coins without looking. What is the probability that the boy’s friend will choose the quarter as one of the two coins? Show your answer in fraction and percent, round to the nearest whole percent.

Answer 1

No of objects=5

`\begin{gathered}\\ \sf {P(Quarter)}\end{gathered}`

`\begin{gathered}\\ \sf (1)/(5)\end{gathered}`

`\begin{gathered}\\ \sf 20\%\end{gathered}`

Answer 2

• No of objects=5

`\\ \rm\longmapsto P(Quarter)`

`\\ \rm\longmapsto (1)/(5)`

`\\ \rm\longmapsto 20\%`
