Answer:

[tex]P(M\ or\ N) = 0.80[/tex]

Step-by-step explanation:

Given

[tex]P(M) = 0.70[/tex]

[tex]P(N) = 0.50[/tex]

[tex]P(M\ and\ N) = 0.40[/tex]

Required

Calculate P(M or N)

This is calculated using:

[tex]P(M\ or\ N) = P(M) + P(N) - P(M\ and\ N)[/tex]

The equation becomes

[tex]P(M\ or\ N) = 0.70 + 0.50 - 0.40[/tex]

[tex]P(M\ or\ N) = 0.80[/tex]
