Using relationship
P(E or F) = P(E)+P(F)-P(E and F)
Substitute
P(E or F)=0.20+0.35-0.10
or
P(E or F)=0.45

Probabilities are used to determine the chances of an event.

The value of P(e or f) is 0.45

The given parameters are:

[tex]\mathbf{P(e) = 0.20}[/tex]

[tex]\mathbf{P(f) = 0.35}[/tex]

[tex]\mathbf{P(e\ and\ f) = 0.10}[/tex]

P(e or f) is calculated using:

[tex]\mathbf{P(e\ or\ f) = P(e) + P(f) - P(e\ and\ f)}[/tex]

So, we have:

[tex]\mathbf{P(e\ or\ f) = 0.20 + 0.35 - 0.10}[/tex]

[tex]\mathbf{P(e\ or\ f) = 0.45}[/tex]

Hence, the value of P(e or f) is 0.45
