Question

a dice is thrown once. find the probability of getting a perfect square composite number

Answer 1

Dear student
$$\begin{gathered} \mathrm{Total}\mathrm{outcomes}\mathrm{when}\mathrm{a}\mathrm{dice}\mathrm{is}\mathrm{thrown}\mathrm{once}=6 \\ \mathrm{Perfect}\mathrm{squares}\mathrm{are}1\mathrm{and}4\mathrm{but}\mathrm{perfect}\mathrm{square}\mathrm{number}\mathrm{which}\mathrm{is}\mathrm{composite}\mathrm{is}\mathrm{only}4 \\ \mathrm{So}\mathrm{required}\mathrm{probability}=\frac{\mathrm{favouable}\mathrm{outcome}}{\mathrm{total}\mathrm{outcome}}=\frac{1}{6} \end{gathered}$$
