Question

May you please help me with the Y’ (prime) part

Answer 1

From the Venn Diagram, there are 2 yellow marbles and there are a total of 10 marbles.

The formula for calculating the probability of an outcome is given by

`P(x)=\frac{\text{Number of required outcomes}}{Total\text{ number of outcomes}}`

Therefore, the probability of picking a yellow marble can be calculated as

`P(Y)=(2)/(10)=(1)/(5)`

Hence, the probability of not picking a yellow marble is given by

`P(Y^(\prime))=1-(1)/(5)`

Therefore,

`P(Y^(\prime))=(4)/(5)`
