Answer:
The probability that she uses gray or yellow is 0.93
Step-by-step explanation:
Suppose, [tex]G[/tex], [tex]B[/tex] and [tex]Y[/tex] represent the events of using gray, blue and yellow colors respectively.
So, [tex]P(G)= 0.80 , P(B)= 0.70[/tex] and [tex]P(Y)= 0.75[/tex]
The probability that she uses gray and yellow is 0.62 , that means [tex]P(G \cap Y)= 0.62[/tex]
The formula we will use here: [tex]P(G\cup Y)= P(G)+P(Y)-P(G\cap Y)[/tex]
According to the above formula.....
[tex]P(G \cup Y)= 0.80+0.75-0.62\\ \\ P(G\cup Y)= 0.93[/tex]
So, the probability that she uses gray or yellow is 0.93
