Answer:

P(G\ then\ R)=0.045

Step-by-step explanation:

From the question we are told that:

Percentage of  Green beads P_g=18

Percentage of  Red beads    P_r=18

Percentage of Purple beads P_p=18

Therefore

Probability of choosing a Green bead is

 P(G)=0.18

Probability of choosing a Red bead is

 P(R)=0.25

Generally the equation for choosing a green bead then a red bead is mathematically given by

Since Outcomes are independent

 P(G\ then\ R)=0.18*0.25

 P(G\ then\ R)=0.045
