If 18 percent of the beads in a bag are green, 25 percent are red and 40 percent are purple. What is the probablity of choosing

sweet [91]

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

$P(G\ then\ R)=0.18*0.25$

$P(G\ then\ R)=0.045$
