Question

Given that the avobe spinner is fair, what is the probability of getting a blue, green or red?

• A. $P(Blue,Green,Red)=\frac{1}{6}$
• B. $P(Blue,Green,Red)=\frac{2}{5}$
• C. $P(Blue,Green,Red)=\frac{1}{2}$
• D. None of the above

Answer 1

The correct option is C $P(Blue,Green,Red)=\frac{1}{2}$

Number of favourable outcomes: $\{Blue,Green,Red\}$$=3$

Total number of outcomes $\{Blue,Green,Red,Yellow,Pink,White\}$$=6$

Hence, $P(Black,Green,Red)=\frac{3}{6}=\frac{1}{2}$
