Answer:

[tex]P(E\ or\ F) = 0.60[/tex]

Step-by-step explanation:

Given

[tex]P(E) = 0.25[/tex]

[tex]P(F) = 0.40[/tex]

[tex]P(E\ and\ F) = 0.05[/tex]

Required

Determine P(E or F)

This is calculated using:

[tex]P(E\ or\ F) = P(E) + P(F) - P(E\ and\ F)[/tex]

[tex]P(E\ or\ F) = 0.25 + 0.40 - 0.05[/tex]

[tex]P(E\ or\ F) = 0.60[/tex]
